Hello,

It would be nice to be able to provide a character substitution list when naming files from tags.

As an example, my initial motivation was to being able to substitute the slash ASCII character '/' with a division slash unicode character '∕' instead of an underscore.

But it would be good too to make accessible to the user the mapping between characters to replace and what to replace them with, with the "Replace non-ASCII characters" option (but not only).
