I'm sure if you were to extend the default to include more hebrew characters nobody would complain, but I don't really see a question here? Assuming that you just intend to provoke discussion, I've moved this to feature ideas.
Indeed, there's no question here. I did not intent to provoke a discussion, but only to notify the need of this to be done.
I use this post as a reference to ask for assistance on IRC, and to point other users of this issue. I don't have a patch to solve this, and this is not a bug, so I thought it is inappropriate to post a FlySpray issue for that.
Please keep this post open in Feature Ideas, so we can relate to it until this issue is resolved.
