[Libreoffice] be-BY and ns locale codes in LibreOffice

[Andras Timar]

Hi,

Do you know why 'be-BY' code was used in LibreOffice instead of
simpler form 'be' (Belarusian)?
Do you know why 'ns' was used instead of the standard (ISO 639-2)
'nso' for Northern Sotho?
If I replace them, i.e. be-BY -> be and ns -> nso, can it break anything?

Thanks,
Andras
