[Solved] Cyrillic characters in spoiler tag

This discussion is related to the Spoilers addon.

All is fine when I use Latin characters:
[spoiler=test]test[/spoiler]
But the spoiler is not displayed correctly when I use the Cyrillic characters:
[spoiler=тест]test[/spoiler]

How can I fix it? I use Vanilla 2.0.18.1. Thanks in advance you for answers.

Found the answer. It is necessary to change the line 57:
$Data->Body = preg_replace_callback("/(\[spoiler(?:=\"?([\d\w_',.? ]+)\"?)?\])/", array($this, 'SpoilerCallback'), $Data->Body);
to:
$Data->Body = preg_replace_callback("/(\[spoiler(?:=\"?([\d\w_абвгдеёжзийклмнопрстуфхцчшщъыьэюяАБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯ«»',.? ]+)\"?)?\])/", array($this, 'SpoilerCallback'), $Data->Body);

I would be grateful if someone will confirm or disprove the correctness of this decision.

use [\d\p{L}_',\.\?]+

that will match any kind of letter in any language.

[\d\w\p{Cyrillic}_',\.\?]+

for Cyrillic and standard Latin

Sorry, x00, but it doesn't work. Does p{L} and p{Cyrillic} ranges include " character? It may be a cause of problem, I guess.

I think you need the u modifier so

$Data->Body = preg_replace_callback("/(\[spoiler(?:=\"?([\d\p{L}_',\.\?]+)\"?)?\])/ui", array($this, 'SpoilerCallback'), $Data->Body);

the i modifier makes it case insensitive.

you could try а-яА-Я

the prior example is dependent on you version of php and PCRE

It works with string:
$Data->Body = preg_replace_callback("/(\[spoiler(?:=\"?([\d\p{L}_\-—«»',.?! ]+)\"?)?\])/ui", array($this, 'SpoilerCallback'), $Data->Body);

Thank you for your help, x00.

No worries my friend.
