Is there a standard way to handle diacritics in URLs for CI?

Hello - I've not worked with CI for a couple of years so I may have missed a development in this area.

Is there a standard way to handle creating url_title type strings from strings that contain diacritics? If I wanted to map Résumé to /about-me/resume/ - has anyone created a way to do it?
