A Guide to Using Pictograms in Mobile Applications

A long-standing feature

Developers inspecting the user agent profile of a modern handset like the
Motorola XT682 ATRIX TV may be surprised to discover the following ImageCapable declaration which indicates whether a device can display images or not:

This clause is a remnant from a time when mobile phones boasted displays that
showed just a few lines of monospaced characters and could not render bitmap
images. As a remedial feature, mobile clients included a set of glyphs conveying
stereotypical representations of actions, states and objects. These graphical
symbols, frequently stored as a special font in the terminal, could be referred
to in Web pages and served as a substitute for richer, but unprocessable pictures.
(HDML, a markup
format for the mobile Web elaborated in the mid-1990s, offered a syntactic
construct to this effect).

Pictograms were soon considered to be useful as such, and made their way into
i-Mode, WAP and UNICODE specifications.

Pictograms differ from icon resources of native smartphone applications:

  • They are not specific to a single program, but are standard symbols accessible
    from all Web applications. The drawback is that their pre-defined style does not
    allow for a brand or organization-specific look-and-feel.
  • They do not have to be explicitly installed, for they are built in the client
    software. Relying upon pictograms potentially reduces network traffic, as the
    corresponding images need not be downloaded to the terminal.
  • Because they are usually handled like characters, it is straightforward to embed
    them in a normal text flow. On the other hand, they are often unsuitable as
    components of a graphical user interface.

Whether in household appliances, packaging, or car dashboards, pictograms are ubiquitous in daily life; their application in mobile services is thus a natural step.


Symbols with easily recognizable semantics can improve the usability of mobile Web
applications when used judiciously, for example in the following cases:

  1. Distinguishing similar elements from each other In the mobile Web, a clickable link may serve to navigate to another Web page;
    to initiate a file download; to establish a telephone call or a video call; to
    send an SMS, an MMS or an e-mail. A pictogram identifies the type of action
    corresponding to each URL.
  2. Drawing attention to specific items A pictogram makes elements with important properties stand out:

    • marking items in a list which have been recently modified;
    • tagging those form fields that contain erroneous values;
    • signalling that the activation of a button or a link entails a side-effect.

  3. Summarizing information If a picture is worth a thousand words, a pictogram is possibly worth a
    short sentence – as demonstrated by entrenched practices and conventions:

    • railway timetables rely upon symbols to condense instructions such as “seat
      reservation is compulsory”, “runs only on Saturdays”, etc;
    • tourist guides summarize the description of an accommodation with symbols
      for the hotel category and its amenities;
    • meteorological forecasts provide overviews constructed out of images for
      each weather condition (e.g. “heavy snow shower during the day”).

  4. Expressing concepts Pictograms act as signifiers so that textual expressions of those concepts
    are never employed. Well-known instances are emoticons and traffic signs.

examples of pictograms

The preceding picture illustrates various forms of pictograms. From left
to right: a WAP XHTML document with symbols identifying link types; a typical
i-Mode page generously spiced with emojis; and a Wikipedia article showing
support for ISO pictographs on an Android handset.

Just like with many other aspects of the mobile Web, the deployment of this
venerable, albeit little-known building block must cater for various generations
of competing standards and discrepancies between implementations. In the following,
we survey the ways to declare pictograms in mobile Web pages and provide
correspondence tables between relevant symbol dictionaries.

Openwave icons

The browser developed by the firm Openwave (formerly called Unwired Planet, then
phone.com, today Myriad) is the longest serving mobile Web client in existence,
and is still deployed on numerous handsets with limited hardware capabilities.
It supports a form of pictograms identified by name or by number:

The syntax works in XHTML and WML. Attribute localsrc takes
precedence over src and alt, in both cases displaying
the pre-defined icon star2.
The numbering scheme is recommended. Recognizing an Openwave browser is
easy, since its user agent identifier matches the egrep/Perl pattern:

(UP.Browser/[0-9.]+)|([Oo]pen[Ww]ave[/ ]?[0-9.]+)

Version Icon range Remarks
≥ 4.1 1 – 175 The browser implements WML
≥ 5.0 1 – 175, 500 – 518 The browser also implements XHTML
≥ 6.1 1 – 175, 500 – 536
≥ 6.2 1 – 175, 500 – 561 The browser supports WAP pictograms

Nowadays, the original Openwave browser documentation can be retrieved only
from the Internet archive.

To this day, the Japanese operator KDDI commercializes phones featuring
Openwave software which, depending on the device class, incorporates built-in
icon sets supplementing the basic dictionary, or retrieves them as external

Class Icon range Remarks
A, B 1 – 175 176 – 330, 500 – 518 as downloadable images; old models
C (1) 1 – 304 305 – 330, 500 – 518 as downloadable images; old models
C (2) 1 – 304, 500 – 518
D (1) 1 – 334 some models with animated icons
D (2) 1 – 518, 700 – 822 some models with animated icons
D (3), F 1 – 518, 700 – 828 some models with animated icons in D; no animations in F

KDDI publishes on its WWW site a correspondence table between handset models
and supported icon ranges. Although all pictograms are assigned names, they
are usually embedded in Web pages with the Openwave numbering scheme.

Icons in overlapping ranges are compatible across all Openwave devices, but
slight variations exist: several arrows pointing straight upwards or downwards
(numbered 42, 43, 70, 71) become oblique in later implementations, whereas some
simple triangles become doubly tipped ones (7, 8, 34, 35).

WAP pictograms

The WAP standard from the Open Mobile Alliance comprises a dictionary of
62 core and 205 optional pictograms, markup to declare them, and a fall-back
mechanism in case a symbol is not implemented in the handset. In XHTML mobile

The browser outputs the pictogram for new if locally available;
otherwise, it downloads the file indicated in the img tag,
or displays the string in the alt
attribute if the image itself cannot be rendered. Older browsers (such as
Motorola MIB) may subject pictograms to the same restrictions as external
bitmaps – for instance enforcing a limit on the number of images that can
appear on a Web page.

The local presence of specific symbols may vary from a browser version to
another; the following compatibility table therefore considers whether the
client software recognizes the WAP pictogram syntax and defaults correctly
to an external image when appropriate.

OS / Browser Vendor Version Support Remarks
Android Google ≤ 4.1 no displays error placeholder
Bada / Dolfin Samsung ≥ 2.0 partial uses the fall-back
Blackberry RIM ≤ 7.1 partial uses the fall-back
iOS / Safari Apple ≤ 6.0 no error alert, empty placeholder
Meego Nokia ≥ 8.5 partial uses the fall-back
MIB Motorola ≥ 2.2 yes core set; emotion set ≥ 2.2.1
Mobile IE Microsoft ≤ 9.0 partial uses the fall-back
NetFront Access ≥ 3.2 yes implements the core set
Obigo Teleca ≥ Q05A yes implements the core set
Opera Mini Opera ≥ 4.0 partial uses the fall-back
Opera Mobile Opera ≥ 10.0 partial uses the fall-back
S40 Nokia ≤ 6th ed. no displays error placeholder
SEMC SonyEricsson ≥ 4.0 yes implements the core set
Symbian Nokia < 7.0 partial uses the fall-back
≥ 7.0 no displays empty placeholder
TSS Samsung ≥ 2.5 partial uses the fall-back
UP.Browser Openwave ≥ 6.2 yes implements the core set

It appears that, while most browsers recognize the syntax declaring WAP
pictograms, this feature is fully supported only by legacy browsers not
based on Webkit and explicitly preferring XHTML mobile profile over HTML
and XHTML basic. This presumably excludes the newest generation of the
NetFront (NX), Obigo (v. 10) and Myriad (Openwave v. 9) software built
upon Webkit, which could not be tested at the time of this writing. One
should also keep in mind that interactive mobile Web validators such as
are geared towards XHTML basic, and hence may erroneously flag WAP
pictograms as mobile-unfriendly resources.

The official reference for WAP pictograms is published on the
WWW site.

ISO pictograms

ISO normalized numerous pictograms with
UNICODE 6.0, refining proposals
originally submitted by Google and Apple to harmonize Japanese emojis.
The corresponding code points are reserved
in various blocks of the UNICODE space, chiefly “miscellaneous symbols and
pictographs”, “emoticons”, and “enclosed alphanumerics supplement”; blocks
“transport and maps”, “miscellaneous symbols and arrows”, “miscellaneous
symbols”, “dingbats”, “enclosed alphanumerics” also contain useful pictograms.

Web pages access all these symbols via numeric character references:

ISO pictographs are thus dealt with exactly like characters; there is no
graceful fall-back if the necessary font is not installed in the
terminal – missing glyphs might appear as question marks, black squares, or
blank spaces. Absent a Javascript routine to test the existence of specific
glyphs on a client, support for ISO pictograms must be determined on the
application server via a device description repository.

Since they are resources of the operating system, pictographs are in principle
not tied to the browser and are available to other software modules as well.
However, because of their intrinsic nature as characters, some caution is required:

  • Several character blocks of interest are located in the UNICODE Supplementary
    Multilingual Plane. Third-party applications do not always handle characters
    outside the Basic Multilingual Plane properly. As a consequence, some symbols
    may be correctly displayed, while others are unrecognised. This appears to be
    the case with Opera Mobile, which does not render all standard ISO pictographs
    enabled on Android 4.1.
  • Pictographs are usually provisioned through the default system typeface built
    in the terminal. They may become inaccessible if the user switches his browser
    or general user interface preferences to a different font.
  • Content styled with specific typefaces raises similar problems. Regrettably, CSS
    offers no construct to force a textual element or a numeric character reference
    to be rendered in the context of the default client font.

In the following, we consider the pictograms listed in tables of sections
7 and 8.
IPR symbols refer to signs for “copyright”, “trademark”
and “registered trademark”.

OS Version core emotions Remarks
Android ≥ 4.1 partial yes Extensive coverage of the ISO norm, with just a couple of omissions in the core dictionary.
Bada ≥ 2.0 no no Supports circled digits, IPR symbols and a couple of isolated pictographs.
iOS ≥ 6.0 yes yes Exhaustive provision of “emoticons” and “miscellaneous symbols and pictographs”.
Meego ≥ 1.2 no no Circled digits, most arrows, IPR symbols and a handful of other pictographs.
Symbian ≥ Belle no no Implements circled digits 1 to 9, IPR symbols and the single traditional smiley.
Windows Phone ≥ 7.5 partial yes Good coverage, except for some blocks like “miscellaneous symbols and arrows”.

With Bada, BlackberryOS, Meego, Symbian and WebOS being either wound down,
neglected or undergoing an uncertain overhaul, support for ISO pictographs
is likely to remain the preserve of Windows Phone, iOS and Android in the
foreseeable future. Only Nokia S40 might be in a position to adopt this
feature in the short term.


Mobile applications developed in the Far East rely extensively on pictograms.
The Japanese mobile Web is a world unto itself, and its implementations of
pictograms (called emojis) exhibit a number of peculiarities:

  • Each mobile network operator (Willcom, Softbank, NTT DoCoMo, KDDI) defines
    its own set of emojis. While dictionaries overlap, there is no bijective
    relation between them.
  • Just like with ISO pictographs, Japanese emojis correspond to symbols in
    the code space of the document character set. However, because of legacy
    character encodings, character references vary depending on whether Web
    pages are formatted in a UNICODE-compliant encoding (such as UTF-8) or
    not. For instance, the new symbol in i-Mode is represented by decimal
    character reference in pages encoded with
    Shift_JIS (corresponding to code point 0xF982 in the Shift_JIS space),
    but by the hexadecimal reference in pages encoded
    with UTF-8.
  • In some environments, a pictogram may be directly entered as a sequence of
    bytes corresponding to its character encoding.
  • The set of emojis and their encoding may differ amongst user agents in the
    same device (for instance the electronic mail client and the browser).

This article at mobiForge
clarifies the underlying concepts and the intricacies of character encoding.

Operator Dictionary Emoji Representation of symbol “telephone call”
DoCoMo 2 levels
252 symbols max.
DoCoMo phone call (Shift_JIS)
KDDI 7 levels
647 symbols max.
KDDI phone call (Shift_JIS)
Softbank 6 levels
485 symbols max.
Softbank phone call chr(27).'$E$'.chr(15) (PHP string equivalent of Shift_JIS binary code)
Willcom 2 sets
163 symbols + 252 i-Mode emojis
Willcom phone call (Shift_JIS, Willcom-specific)
(Shift_JIS, i-Mode compatible)

Operators have published (mainly in Japanese) detailed documentation about
their versions of emojis; they can be obtained from the WWW sites listed above.
Comprehensive correspondence tables describing how to insert emojis into Web
pages are presented at trialgoods.com.
In 2012, Japanese operators harmonized the design of their pictograms in the
style of i-Mode emojis.

Emojis are so popular that Apple was compelled to implement a version derived
from the Softbank dictionary upon launching the iPhone in the Japanese market.
Version 5.0 of iOS also made these pictograms generally available to non-Japanese
iPhone models after a reorganisation to comply with the ISO norm – which implies
that pre- and post-iOS 5.0 devices refer to emojis through separate numeric ranges.

iOS version emojis Remarks
≥ 2.2.1 469 pictograms stored in a private code space
e.g. symbol glowing star:
≥ 5.0 468 most pictograms re-mapped to standard UNICODE ranges
e.g. symbol glowing star: 🌟
≥ 6.0


The site iemoji.com lists each
iOS emoji with its numeric encodings.

Core dictionary

While there is ample on-line documentation about finding equivalent
symbols in Japanese emoji dictionaries, such information is sorely
lacking for the formats used in the rest of the world. We present here
a correspondence table between WAP, Openwave, ISO, and iOS pictograms.
The entries are organized according to the core WAP dictionary, and
therefore deal with a limited subset of the standards under consideration.
This is justified on the following grounds:

  1. The entire set of potentially relevant symbols defined by ISO inside
    various UNICODE character blocks amounts to well over 1300 items, and
    would at any rate result in an unwieldy table.
  2. Feature phones, most of them running a WAP or Openwave browser, currently
    represent about 75% of the installed base of handsets worldwide.
  3. The core dictionary covers the most commonly useful symbols, and, to our
    knowledge, is the only one to have been fully ported to WAP terminals.

Hence, these tables should prove especially useful when setting up universally
accessible mobile Web sites – despite the fact that several pictograms
(especially “beginner”, “clear” and
“toll-free”) betray their Japanese
origins. Developers exclusively targeting modern smartphones need only
refer to the ISO norm when inserting pictograms in their applications.

Values are hexadecimal references to code points in the UNICODE space, and
images exemplary depictions of the associated symbols. Sometimes, an operating
system provisions the pictogram via a different UNICODE character, whose code
point is then mentioned explicitly. We suggest approximate substitutes whenever
a straightforward translation from one dictionary to another is infeasible:

  1. No direct match; entry is a proposed surrogate.
  2. iOS implements these pictograms through UNICODE combining character
    sequences (numeral followed by an enclosing keycap) – a feature rarely
    present elsewhere. Relying upon “circled digits” instead is more portable.
  3. These symbols are more generic than ISO labelled arrows at code points
    U+1F51D (“top”), U+1F51C (“soon”),
    U+1F519 (“back”).
  4. ISO character U+1F22F embodies exactly the meaning of “reserved”
    (e.g. seat reservation), but is a Japanese ideogram. The proposed replacement
    is more suitable for other countries.
  5. Already available in Android version 1.6.
  6. Only available in iOS since version 6.0.

Emoticon dictionary

Class “emotions” is the sole subset of the optional WAP dictionary
that has enjoyed some (modest) level of support in mobile phones. It comprises a
number of smileys for which we propose equivalent iOS, ISO and Openwave
representations. This table also applies the tweaks and descriptive conventions
used for the core dictionary.

Smileys have long been extremely popular in messaging applications and
Internet discussion forums. Every major platform (Yahoo! Messenger,
Microsoft Messenger, America Online, among others) offers a rich set
of icons to let users liven up the texts they send to each other.
Emoticons are entered as pre-defined identifiers or character sequences
(for instance :-) or 8-|).
The messaging clients of some mobile operating
systems (notably Windows Phone) follow a similar approach.

Service platforms

Unfortunately, major device description repositories provide very few
data describing pictographic terminal capabilities. Developers may resort
to attributes such as the type of browser or the version of the operating
system run by the handset in order to fine-tune the representation of mobile

DDR Attribute Values Description
51 degrees no specific attributes available
Detect Right supportedpictogramset array of literals List of WAP pictogram classes implemented (from UAProf).

Handset Detection no specific attributes available
WURFL emoji true / false Indicates support for i-Mode emojis.
opwv_xhtml_extensions_support true / false Indicate support for Openwave icons and other proprietary extensions.
opwv_wml_extensions_support true / false

Programs that map pictogram dictionaries and encodings to each other
are necessary when generating content for terminals implementing
different pictographic formats, or when exchanging messages amongst
them. Here is a sample of public-domain tools that translate between
popular Japanese conventions.

Only UNICODE encoding. DoCoMo codes erroneously assumed identical to those of KDDI.
PHP yes yes yes no partial yes
Only UNICODE encoding. Although not explicitly supported, iOS pre-5.0 uses Softbank codes.
PERL yes yes yes no partial no
Shift_JIS and UTF-8 encodings. Although not explicitly supported, iOS pre-5.0 uses Softbank codes.
We are not aware of any similar gateway utilities for ISO, Openwave and WAP.

Concluding remarks

The interest in pictograms was rekindled when Apple released an iPhone
model with an abundant collection of colourful icons embeddable in
applications and Web pages. The revision of UNICODE published in October
2010 increases the relevance of pictograms for smartphones, but feature
phones and legacy handsets have long been endowed with a comparable
capability – albeit via different mechanisms. The information presented
in this article should enable developers to decide how to integrate
pictograms in their Web sites – taking into account requirements about
application look-and-feel, the range of targeted devices, and the facilities
to configure their Web service platform with pictogram generators.

We recommend a utilization of pictograms more parsimonious than what one
can often observe in Asian mobile Web sites. Hence, the core dictionary
should suffice for the first couple of – very common – scenarios listed
in section 2.

Beyond this basic set, ISO specifies a profusion of idiosyncratic signs
for the Chinese horoscope, Japanese places and holidays, Nippon cuisine,
service ideograms, manga characters, as well as more universally interesting
pictographs related to office supplies, commercial and professional activities,
sports, games, vehicles, plants, animals, the weather, geometric shapes and
additional emoticons. WAP defines many optional items that map easily to
those ISO code points, but lacking support in WAP handsets makes this
compatibility immaterial in practice. On the other hand, about 160 actual
Openwave icons correspond to symbols scattered throughout UNICODE and may
prove occasionally useful when catering for low-end devices. Developers
can peruse the Openwave documentation to ascertain the equivalence of
individual pictograms on a case-by-case basis. Sites such as
shapecatcher.com and
have query tools that facilitate the exploration of the UNICODE character space.

Of course, the situation may arise where the symbol of interest is completely
unsupported by a handset or a standard. The manipulation of custom icons
(such as those used in the present article, extracted from the
fatcow collection of free icons)
is an issue to be addressed in another instalment.
