[Mediawiki-i18n] Localized Magic Words and ?uselang=<code>

[Eugene Zelenko]

Hi!

Is it possible to account localized magic words in system messages
when viewing arbitrary wiki (most interesting is Commons) with adding
?uselang=<code> to address?

Or only English magic words could be used in system messages?

I played with Commons, and Belarusian PLURAL function is selected
properly, but I need to change МНОЖНЫ_ЛІК to PLURAL (and other magic
words too) in MessagesBe.php.

Thank you for comments,
Eugene.
