@flandrei Hm, I can't figure out how that code is working JS isn't my strongest area though, so there may be someone else who can help you.
It can not contain letteres like "ă". In my opinion it is because this letter is not containet in this file.
I think that you're correct, but I can't tell how you'd add it into the file. I hope you're able to solve it! I'll work on it some more soon to see if I can figure it out.
