In koha translate page, the language 'Bengali' is listed, but the files are named as "*bn-IN*-pref.po" [http://translate.koha-community.org/bn/17.11/]. Our kind request to koha translation maintainer to please rename this to bn-BD as BD refers to Bangladesh where IN referring to India. In addition, we have a history regarding our Bengali Language where 21 February is been celebrated worldwide as a "International Mother Language Day" [https://en.wikipedia.org/wiki/International_Mother_Language_Day] -- *Best wishes.* *--------------------* *Md.
