Torrent download fails when a colon is in the filename

[alexlehm]

I have used Transmission to download video files from a Peertube instance which apparently puts the complete video title string into the filename of the torrent file.

This way I ended up with a file called Bandname: Title1 / Title2-1080p.mp4 which couldn't be created in Windows and made the download fail.
I assume the colon is an invalid character and the / may be a problem as well, though this might work if the directory can be created.

I wonder if it would be possible to "sanitize" the filename and replace the invalid Windows characters like : " and so on or to ask for an alternate filename if creation of the file fails. (using transmission-remote.exe)

Also, if the directory ends with a space, it does not work well with Windows

Bandname: Title1 / Title2-1080p
results in a directory "Bandname: Title1 which confuses Windows, though it is possible to create the dir

Sanitizing is already in place since 3.00, unless it broke in 4.x (I didn't test). Which version are you using?
