Hi! First timer here... So bare with me explaining (and in English).

I've used the MP3tag for a couple of ten thousand files and it's been a Big help. The program is great with it's extensive script options for tag and filename importing and exporting.

I was about to ask a guestion of the function Tag-\>filename. Is there a way to automatize the substitution of characters which use is restricted in filenames but do exist in the song title in tag?

For example, when you use the tag-\>filename -function for a lot of audio files at the same time which' tags contains characters in song names restricted in filenames, for example question marks (?), wich you would like everytime to be substituted with under scores (_). Can it be set somewhere in the program to automaticaly substitute the restricted characters in file naming with the characters you can pre-set - very often dash (-) or underscore (_) depending of the original character to substitute?

In my opinion, if I'd get to choose which name I'd prefer more for an MP3-file titled "Tell me why?", a "01 - Tell me why.MP3" or "01 - Tell me why\_.MP3" I'd definitely choose the latter becouse it's obvious that there belongs a question mark filling the underscore.

If this option is not available in the application, this would surely be one of the good things to add for the coming versions IMO - otherwise the app is pretty much perfect even for more advanced user. For e.g. the audio-CD ripper CDex has this option, altough it's not done even nearly perfectly.
