Unicode Filenames

Since some weeks there is a problem with file named in Unicode. Earlier they were no problem. Now I receive an error message if characters of the Unicode in the filename (ü, ö, ä, ß etc.).
The problem is that I get this error message for older files too if I want to change something on the import page.
The effect is that you can play the audio but you are not able to stop the audio and adjust it. I’m not sure if you have recognized this. It is kind of a problem because I’ve uploaded lots of audios and some of them contain Unicode. Also it could be a problem for external audio sources. I remember that some members reported problems with the audio control. Maybe that is the reason.

@Vera - We’ll look into it. This problem was resolved before but may have come back with the recent changes.
