Description jekhor@gmail.com 2023-06-06 08:29:51 UTC 
SUMMARY
***
The Region and Language KCM has a strange heuristic for mapping Plasma language to GLibc locale in the KCMRegionAndLang::constructGlibcLocaleMap(). This algorithm can select almost unused locale variant instead of expected one. For example, it selects a be_BY@latin locale for Belarusian language instead of pure be_BY.
***

STEPS TO REPRODUCE
1. Run Region and Language KCM
2. Select a Belarusian ("беларуская") language
3. Apply changes
4. Check the ~/.config/plasma-localerc for LANG variable

OBSERVED RESULT
LANG=be_BY.UTF-8@latin

EXPECTED RESULT
LANG=be_BY.UTF-8

Comment 1 Joshua Goins 2023-06-07 23:23:07 UTC 
Can confirm, we should have a better heuristic in this case. Thanks for pointing out the specific function that's the issue too!
