This ticket is to add language codes for the representations of lemmata and forms in a number of languages:
* Hausa in the Arabic script (Ajami), since Hausa is one of the focus languages of the Abstract Wikipedia;
* Manchu, as a language written in the Mongolian script whose code is less controversial than mvf;
* Sumerian (in its cuneiform and Latin-script representations), because we have L1 and it, out of all lexemes, should at least be modeled correctly;
* German Sign Language, by analogy with the American equivalent having one and the British one being requested in another ticket; and
* Klingon (in its pIqaD and Latin forms), so that those processing lexemes in that language can better process it.
The first three have some publicly available resources listed [[ https://www.wikidata.org/wiki/Wikidata:Lexicographical_data/Documentation/Resources | on this page ]], while the last two at least have non-endangered communities using them.
