Windows build does not handle non-ASCII filenames

[ylqhust]

i run this command:
audiowaveform-win32.exe -b 8 --pixels-per-second 10 -i "TWICE (트와이스) - FANCY.mp3" -o out.json

get this:
Failed to read file: TWICE (????) - FANCY.mp3
Invalid argument

It looks like the Windows build of audiowaveform doesn't handle non-ASCII characters on the command line. For now, I can only suggest renaming the file, as a workaround.
