I understand that complaining on something free is not really correct but I would suggest to concentrate on fixing autocomplete on existing languages rather than adding new ones. Autocomplete (autocorrect?) on Russian is terrible. Lots of words are missing and it autocorrects correctly written word to incorrect.
Exame: I typed отвага and keyboard have autocompleted it to отвагу
It also can't understand the sentence itself so tens of suggested words are lincorrect too.
Thanks
