== Usage ==
This module provides functions that access information on Unicode code points. The information is retrieved from data modules generated from the [https://www.unicode.org/Public/UNIDATA/ Unicode Character Database], or derived by rules given in the [https://www.unicode.org/versions/Unicode11.0.0/UnicodeStandard-11.0.pdf Unicode Specification]. It and its submodules were copied from English Wiktionary and then modified; see [[wikt:Module:Unicode data|there]] for more information.

==Parameters and functions==
===code point===
The code point is to be entered as '''hexadecimal value'''. For example, {{unichar|A9|COPYRIGHT SIGN}}:
:{{mono|1={{!}}A9<sub>hex</sub>}}
:{{mono|1={{!}}0xA9<sub>hex</sub>}}
:{{mono|1={{!}}0x00A9<sub>hex</sub>}}
:{{mono|1={{!}}0x00a9<sub>hex</sub>}}
:<code><nowiki>{{#invoke:Unicode data|lookup|name|0x00A9}}</nowiki></code> &rarr; {{#invoke:Unicode data|lookup|name|0x00A9}}

Incorrect or unintended results:
:{{mono|1=169<sub>dec</sub>}}: <code><nowiki>{{#invoke:Unicode data|lookup|name|169}}</nowiki></code> &rarr; {{#invoke:Unicode data|lookup|name|169}} {{nay}} &mdash;"U+00A9" {{code|1=&copy;}} expected; but is read as {{mono|1=00A9<sub>hex</sub>}}&nbsp;(that is,&nbsp;{{mono|1={{hex2dec|169}}<sub>dec</sub>}}
:{{mono|1=U+00A9}} <code><nowiki>{{#invoke:Unicode data|lookup|name|U+00A9}}</nowiki></code> {{nay}} &mdash;do not use "U+" prefix
:{{mono|1=غ}} <code><nowiki>{{#invoke:Unicode data|lookup|name|غ}}</nowiki></code> {{nay}} &mdash;cannot enter a character as codepoint

==="{{mono|lookup}}" and "{{mono|1=is}}" functions===
; {{code|lang=lua|lookup, is}}: Template-invokable functions that allow access to the functions starting with <code>lookup</code> and <code>is</code>.For most of the functions, add the code point in hexadecimal base as the next parameter. For <code>is"{{!}}Latin</code>, <code>is{{!}}rtl</code>, and <code>is{{!}}valid_pagename</code>, add character string. [[HTML character references]] in the text are decoded by the module into code points.
:For example, {{tnull|&#35;invoke:Unicode data|is|Latin|àzàhàr̃iyyā̀}} &rarr; {{#invoke:Unicode data|is|Latin|àzàhàr̃iyyā̀}}.

:Internally, in modules, these functions are named using underscore: {{code|lang=lua|lookup_name{{!}}code point}} &larr; {{code|lang=lua|lookup_name}}
:For <code>&amp;A9;</code> <big>&#xA9;</big>: {{tnull|&#35;invoke:Unicode data|lookup|name|A9}}&nbsp;&rarr; {{#invoke:Unicode data|lookup|name|A9}}

==Data modules==
The data used by functions in this module is found in [[Special:PrefixIndex/Module:Unicode data/|submodules]]. Some are generated by [[AWK]] scripts shown at [[wikt:User:Kephir/Unicode|User:Kephir/Unicode]] on English Wiktionary, others by Lua scripts on the <code>/make</code> subpages of the submodules.
* [[Module:Unicode data/age]]: 'Age' of a character, that is: version introduction number.
* [[Module:Unicode data/aliases]]: the formal name aliases for characters (from [https://www.unicode.org/Public/UNIDATA/NameAliases.txt NameAliases.txt])
* [[Module:Unicode data/blocks]]: the list of Unicode blocks (from [https://www.unicode.org/Public/UNIDATA/Blocks.txt Blocks.txt])
* [[Module:Unicode data/category]]: data mapping characters to their General Category (from [https://www.unicode.org/Public/UNIDATA/extracted/DerivedGeneralCategory.txt DerivedGeneralCategory.txt])
* [[Module:Unicode data/combining]]: data mapping characters to their Combining Classes (from [https://www.unicode.org/Public/UNIDATA/extracted/DerivedCombiningClass.txt DerivedCombiningClass.txt])
* [[Module:Unicode data/control]]: data for identifying characters that belong to the General Categories of Separator and Other (from [https://www.unicode.org/Public/UNIDATA/extracted/DerivedGeneralCategory.txt DerivedGeneralCategory.txt])
* [[Module:Unicode data/derived core properties]]:
* [[Module:Unicode data/Hangul]]: data used to generate the names of [[Hangul]] syllables (from [https://www.unicode.org/Public/UNIDATA/Jamo.txt Jamo.txt])
* [[Special:PrefixIndex/Module:Unicode data/names|Module:Unicode data/names/<nowiki>*</nowiki>]] ({{mono|000hh, .., 0E0hh}}; eg [[:Module:Unicode data/names/000|../names/000]]): names
* [[Module:Unicode data/scripts]]: data mapping characters to their Unicode script properties (from [https://www.unicode.org/Public/UNIDATA/Scripts.txt Scripts.txt]).

The name data modules ([[Special:PrefixIndex/Module:Unicode data/names/|Module:Unicode data/names/<var>xxx</var>]]) were compiled from [https://www.unicode.org/Public/UNIDATA/UnicodeData.txt UnicodeData.txt]. Each one contains, at maximum, code points U+xxx000 to U+xxxFFF.

==Known issues==
* Reading data like <code>[[:Module:Unicode data/aliases]]</code> not provided nor documented
* Test fail: <code>lookup_category</code> {{mono|U+FFFF}} (&lt;noncharacter-FFFF>) expected: Cn.
::<code><nowiki>{{#invoke:Unicode data|lookup|category|0xFFFF}}</nowiki></code> &rarr; {{#invoke:Unicode data|lookup|category|0xFFFF}} [Nil]
