calibre has a tendency to replace special characters with _ for filesystem comaptibility reasons. I have a lot of books with multiple special characters (colons, apostrophes, and other punctuation) in both the title and series names, and I tend to use the underlying filesystem to navigate my library on managed devices.

Is there an easy way to change the mapping of many special characters? Regex works well, but single-function mode means that you can only do one character swap per field (unless there's a chaining syntax I couldn't find), and I don't necessarily want to enter a full programming environment just to swap some characters.
