How to find tags with "Combining Character" Diacritics?

Support

Every so often I’ve run into characters in tags that behave strangely. It takes two backspaces to remove them; the first backspace only removes the diacritic symbol. I’ve just learned these are “Combining Characters”.

Can a filter be set that will find tags that contain these characters? Thanks.

You could specifically filter for such characters with something like:
* MATCHES [\x{20D0}-\x{20FF}]
or any other combination listed in the "Unicode range" part on the linked wikipedia page.

You can replace * with any of your field names, like TITLE or ARTIST.
