Special characters in file name crash MPE

[dante]

SE K310i, MPE1.5.9, WinXP SP2

I had in the "Others" folder a strangely named file, that kept crashing MPE. I got it from saving in a page a data URI scheme file, a href="data:image/svg+xml,%3C%3Fxml%20vers.... so the file ended up with % characters in its name.

I replicated the issue, the exact file name is "svg+xml,%3C%3Fxml vers"

It appears it's not the % that's the problem, a similar <a href="data:audio/imelody,BEGIN%3AIMELODY%0D%0AVERSION%3A1.2%0D%0AFORMAT%3ACLASS1.0%0D%0ABEAT%3A240%0D%0AMELODY%3A*5c3r1%0D%0AEND%3AIMELODY%0D%0A">test imelody</a> resulted in the file "BEGIN%3AIMELODY%0D%0AVERSION%3A1.2%0D%0AFORMAT%3ACLASS1.imy" which MPE handles just fine.
