I read through the entire thread after your response. It seems that Matt not only added this to the clean() function, but ALSO added it to the GUI tool, "clean file properties". That's pretty neat.
My offer of a regex was in case the technique used by the built in tool didn't cover a particular case. Hopefully it covers all common cases and no funky regex will be required.
I kinda like regex, but it's weird even to me. I sometimes read my own stuff and say "why did I do this again?". A purpose built tool is way easier. Thanks Matt! (if you are reading)
