Comment 8 for bug 135921

> Thanks for the information. I just need to figure how to turn a filename into latin 1 now :]

its not quite so clear cut, since you also have to be able to turn it back later when you want to access the file again, say for playback. There's currently zero infrastructure to support this sort of thing and encoding has been a very tricksy issue in the past, so we should proceed very carefully with this, probably in a separate branch.
