Subtitle auto-load doesn't work with non-standard chars

setup folder with

IAmLegénd.mp4 IAmLegénd.srt

IAmLegend.mp4 IAmLegend.srt

loading the file without the e acute correctly auto-loads the srt file. loading the file with the e acute doesn't load the srt file

presumably this applies to all complex characters. incidentally, the marquis display of the movie name when it starts shows the square 'bad char' for the e acute.

windows handles this case fine.
