==About RTL==
I am researching RTL scripts. I met this:

* &#x41;
: 0xa9 -- {{#invoke:Unicode data|lookup|name|41}}
: {{#invoke:Unicode data|lookup|script|41}}
: is_rtl: {{#invoke:Unicode data|is|rtl|41}}

* &#x062B;
: 0x062B -- {{#invoke:Unicode data|lookup|name|062B}} [https://www.fileformat.info/info/unicode/char/062b/index.htm]
: {{#invoke:Unicode data|lookup|script|062B}}
: is_rtl: {{#invoke:Unicode data|is|rtl|062B}}

* &#x05E9;
: 0x05E9 -- {{#invoke:Unicode data|lookup|name|05E9}} [https://www.fileformat.info/info/unicode/char/05e9/index.htm]
: {{#invoke:Unicode data|lookup|script|05E9}}
: is_rtl: {{#invoke:Unicode data|is|rtl|05E9}}


* &#x07D6;
: 0x07D6 -- {{#invoke:Unicode data|lookup|name|07D6}} [https://www.fileformat.info/info/unicode/char/07d6/index.htm]
: {{#invoke:Unicode data|lookup|script|07D6}}
: is_rtl: {{#invoke:Unicode data|is|rtl|07D6}}

I'd expect the Arab, Hebr, Nkoo characters to be rtl=true. Am I misunderstanding something? {{ping|Erutuon}} -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 20:58, 9 January 2021 (UTC)
: {{reply to|DePiep}} The invocation <code><nowiki>{{#invoke:Unicode data|is|rtl|05E9}}</nowiki></code> checks whether the literal characters <code>05E9</code> are right-to-left. To check the right-to-leftness of the Hebrew character, put in the literal character or a HTML character reference: <code><nowiki>{{#invoke:Unicode data|is|rtl|ש}}</nowiki></code> or <code><nowiki>{{#invoke:Unicode data|is|rtl|&#x05E9;}}</nowiki></code>. <code>#invoke:Unicode data|is|rtl</code> as well as <code>#invoke:Unicode data|is|valid_pagename</code> and <code>#invoke:Unicode data|is|Latin</code> interpret their arguments as strings rather than code points in hexadecimal because the corresponding functions in the module take strings. (They could take hexadecimal arguments if someone edited the module to add another parameter to tell them to interpret their argument this way.) — [[User:Erutuon|Eru]]·[[User talk:Erutuon|tuon]] 01:02, 10 January 2021 (UTC)

::{{re|Erutuon}} Thanks, will work for me. Great module! (Second code example is <code><nowiki>{{#invoke:Unicode data|is|rtl|&amp;#x05E9;}}</nowiki></code>). -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 17:28, 10 January 2021 (UTC)

* The four characters, is_rtl:
: using &amp;#x...;  {{#invoke:Unicode data|is|rtl|&#x41;}}
: using &amp;#x...;  {{#invoke:Unicode data|is|rtl|&#x062B;}}

== is_pagename ==
:{{resolved}}
In the function {{code|1=is_pagename}}, does "pagename" stand for "blockname"? Or wider? -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 05:17, 27 March 2022 (UTC)
::Resolved: refers to "valid WP pagename", related to [[WP:NCTR]] invalid title characters like "#". -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 11:34, 27 March 2022 (UTC)

== Missing documentation: Hangul, Aliases ==

I am developing the documentation, especially in {{slink|Module:Unicode_data|List_of_functions}}. To completify, can someone point out how or where the data [[Module:Unicode data/aliases|/aliases]] and [[Module:Unicode data/Hangul|/Hangul]] can be retrieved (implementation)?

== is_RTL check? ==

About {{unichar|0634|ARABIC LETTER SHEEN}} [https://www.fileformat.info/info/unicode/char/0634/index.htm]: 

:<nowiki>{{#invoke:Unicode data |is|rtl|0x0634}}</nowiki> &rarr; {{#invoke:Unicode data |is|rtl|0x0634}}

I expect true (is_rtl), right? -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 23:00, 28 March 2022 (UTC)
:Solved: enter the character &lt;ش >, not the U+hex:

: {{done}} I'm not sure I agree with your importing of so many modules from other wikis, but in any event there was never any good reason to comment out that code as opposed to just letting uses of it fail.
