For some time I can't manual update LibreELEC from settings menu in Bulgarian language.
If I change language to English, the update starts.
After some digging for a posible solution, I found that the problem is trigered in service.coreelec.settings/resources/language/resource.language.bg_bg/strings.po
and more precisely in
After more testing with trial and errors I found, that it doesn't accept cyrillic symbols for translation.
If lеаve it empty, the update starts. If enter something in English, the update starts.
Only one symbol in cyrillic and update can't be started.
If more info is needed, please let me know.
