WM6.5 strange characters on youtube client

Hello,

I'm using a custom ROM WM6.5 and everything was working fine. But last week I've noticed that the youtube client for windows mobile I'm using started displaying very strange characters. The numbers appear ok, but for example a search result of "ssss" appears on the search history as strange characters.
I've already removed and installed the app. Also deleted the apps folder from program files and it has always with the same problem:





I've changed region and rebooted but problem remained. I've changed text size, clear type, landscape, problem remains.

Anyone knows what might be causing this behaviour?

Finally I solved it. I renamed /Windows/Fonts to /Windows/Fonts2, restarted the phone and youtube was fine.

Then I moved the files from font2 to font one by one and isolated the ones causing the problem. PROPHHIN is one of then, but there are others that I'm still moving.
