? in mp3 file name for playlists doesn't work

[simoncn]

The forward slash (/) is not a valid filename character. If the ripper is trying to name the folder for the band SS/S using a folder name SS/S, the result will be a folder named SS with a subfolder S. It sounds like either your ripper or your playlist creator has some bugs with how it handles some special characters.

In post #6 you said:

Weirdly though, if I just add a ? to another random file, and add it to a playlist, it doesn't happen. So it does seem to be mostly limited to these specific ones. I can playback the files back normally through minim otherwise, they show up in the correct album and display perfectly.

In post #8 you said:

I just tried a test of taking an mp3 file, adding a ? to the name via OSX finder, adding it to my library and a playlist, and seeing it fail. So it does seem reproducible to some degree.

From these two statements, I'm not clear whether this is working or failing with ? characters that you add manually to a filename without them.
