Depends, it's probably not a highly requested feature because HIVE is heavily English based website, but I have many Arab friends whom I can tell to post things here from time to time if Arabic language actually looked decent here. Many people I know aren't comfortable with English.
To be honest, I'm not sure if you should work on this if it'll take time from other features, but if you want inleo to be "put everything on blockchain app" you'll have to add it eventually.
Hmm perhaps AI will change this
Hopefully.~
