==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}}
