This ticket is to add language codes for the representations of lemmata and forms in a number of languages:
- British Sign Language (bfi), as there are more than 100 lexemes in that language already.
- Paiwan (pwn), as there are a number of users earnestly contributing lexemes in that language of late.
- Middle English (enm), as its lexemes are using an inconsistent combination of "en" and "mis" tags.
