track2track issue when title tag contains '?'

[ghost]

I just bought the Drive soundtrack, used iTunes to rip it to Apple Lossless m4a files for my iPad/iPhone, and then attempted to use python-audio-tools to generate .flac versions for my audio center.

However, track 11 had a question mark in the track title which doesn't seem to get escaped before it is passed to the flac encoder:

$ track2track -t flac -d flac .m4a 01 - Kavinsky & Lovefoxxx - Nightcall.m4a -> flac/Kavinsky & Lovefoxxx - 01 - Nightcall.flac 02 - Desire - Under Your Spell.m4a -> flac/Desire - 02 - Under Your Spell.flac 03 - College - A Real Hero (feat.

Are you trying to write your files to a vfat filesystem? That might explain why Python Audio Tools is unable to generate a file containing a question mark. Try the command:

$ touch "testing?"

in your output directory. If that also has an error, it might help isolate the problem.

In the meantime, I'll see if I can find a portable way of detecting invalid filename characters to prevent these sort of surprises in the future.

Ah yes, I was being stupid and happened to be running on a vfat USB stick at the time, so it was actually just an issue in attempting to create the filename rather than an issue passing the cmdline args to flac encoder.
