Readlang.com has a lot more languages now

I logged into Readlang.com today for the first time in a while, and it looks like the selection of languages has really improved. The first time I used it there were about seven languages and Portuguese wasn't one of them until I contacted the site owner and asked for it to be added. Now as you can see we have the following list to choose from:

So which obvious ones are still lacking? Persian isn't there, nor is Slovak (since Czech and Slovenian are there, Slovak probably should be too). I suppose Croatian as well since Cyrillic Serbian is there. Oh, and "Türk" should be Türkçe. Besides that it is turning into a fairly well-rounded list of options to choose from. I assume Chinese/Japanese/Korean aren't there due to encoding issues.
