error dialog when opening cue file with non-ascii characters

[FelipeLema]

Describe the bug
I get an error dialog when dragging a .cue file with japanese characters. VLC plays the same file just fine.

Steps to reproduce
Explained in bug description.

Expected behavior
Audacious plays the cue file like any other (this one file is the one I have problems with).

Additional information

I can reproduce, but the issue seems to be in libcue. Maybe it does not support UTF-8 properly. The "bad character" error is from here: https://github.com/lipnitsk/libcue/blob/7176a1faccecbfe2d4cca2f776177439ca49cad2/cue_scanner.l#L138

thanks for the quick answer

will open an issue there. If y'all don't mind I'll keep this one open until a version that fixes such issue is pulled in for this repo
