Line 1:

This page attempts to document standards and infrastructure for presentation of Unicode-related information on Wikipedia. It may also serve as a gathering point for work on building the same.

== Glyph images ==

Wikipedia and/or Wikimedia Commons host many images of [[glyph]]s — characters rendered in a given font. In article text, we generally prefer to use literal Unicode characters, not these rendered images. Thus, these images are primarily used in articles ''about'' characters, where an illustration is appropriate. In particular, any [[#Unicode tables]] which provide both the literal character and an image of the character.

Ideally, all such glyph images would be [[vector graphics]], in [[Scalable Vector Graphics|SVG]] format. However, many exist in a [[raster graphics]] format, such as [[Graphics Interchange Format|GIF]]. Converting or replacing these with SVGs is something that should be done.

== Unicode tables ==

Many articles dealing with Unicode include tables of Unicode characters. The standard form for such tables is as given in the following example:.

=== Example table ===

{| class="wikitable sortable"

|+ Unicode Table Example

{{Unicode table header|Example caption}}

! [[Character (computing)|Char]]

! Image

! Name

! [[Hexadecimal|Hex]]

! [[Decimal]]

|-

| {{Unicode|☷}}

|

| [[Ba gua (concept)|Trigram]] for Earth

| U+2637

| 9783

|-

| {{Unicode|☸}}

|

| [[Dharmacakra|Wheel of Dharma]]

| U+2638

| 9784

|-

| {{Unicode|☹}}

|

| White frowning face ([[Emoticon]])

| U+2639

| 9785

|-

| {{Unicode|☺}}

|

| White smiling face ([[Emoticon]])

| U+263a

| 9786

|}

=== Legend ===

:''A copy of this legend, or something like it, will be linked from or displayed with all Unicode tables, once we figure out exactly how that should be done.''

{| class="wikitable sortable"

! Char

| The literal character. If your computer lacks [[Help:Special characters|Unicode support]], you may see [[mojibake|other symbols]] instead of the proper character.

|-

! Image

| A sample image of the character, rendered in an example font.

|-

! Name

| The official name of the character. Additional information may be given in parenthesis.

|-

! Hex

| The numeric [[code point]] for the character, in [[hexadecimal]] (base 16), with [[Unicode#Architecture and terminology|"U+" prefix]].

|-

! [[Decimal]]

| The same code point value, expressed in [[decimal]] (base 10).

|}

=== Design features ===

The table format has the following design features:

Line 80 ⟶ 96:

* "Hex" and "Decimal" columns

** The codepoint number, in both [[decimal]] (base ten) and [[hexadecimal]] (base 16) formats

** Syntax is omitted (e.g.,The “<code>U+</code>”, “<code>&u</code>”prefix is used for hex, “<code>0x</code>”,per the Unicode etc.)standard

** Decimal is not prefixed, per [[WP:MOSNUM]]

** Such syntax is specific to the usage (Unicode specification, HTML, Perl, etc.); it is not a universal form. By omitting it, anyone can copy-and-paste the actual value, and add whatever syntax they need (or none at all).

** Such prefixes also prevent table columns from sorting properly

* The plan is to eventually add some kind of standard explanation of the columns to the tables, most likely as an adjacent template, or maybe links from the headers. Ideas welcome!
