Some software (in my case I'm thinking of MusicIP) cannot handle file and path names that contain diacritical marks (accents, umlauts, etc.: e.g., é, â, ü, ñ). But you may already have a lot of such paths in your music folders. Here is a filter that will find all these files:
`NOT %_path% MATCHES ^[a-zA-Z0-9\W_]*$`

Can anyone show me a filter like this that works?
This one is dated 2012 - and does not.

You could try `%_path%` instead of `%path%`
