Remove Non English Characters

General Discussion
1

I'm fairly ok with MP3 Tag, but I have a problem with non-English characters in the artist field I would like to remove.

For example

Katiana〸攀氀e䑃3

Should be

Katiana

Please help

This should remove any extended character whose code point is above 255 in value ...

Action "Format value" or Convert "Tag - Tag"
Field: ARTIST
Formatstring: $regexp(%ARTIST%,'[[:unicode:]]',)
