Is there a way to remove all punctuation from usernames?

I've created a naming format and enabled:

• remove umlaut accents
• remove all spaces
• trim unwanted spaces and dots

This work really well for those cases, but we do get users with dashes - in their names and occasionally apostrophes ' in them, and I can't find anywhere to remove them.

I've tried adding them to the umlaut accents and replacing them with spaces and hoping one of the other rules will remove the space, but no luck.

Perhaps even a feature that would allow you to use the umlaut accent removal but replace the accent with 'null'

Thanks
