[regex?] How can I remove lines with Chinese characters from the lyrics field?

This is absolutely wonderful. Thank you so much, ohrenkino.

Another kind person had already helped me remove the <> karaoke lyrics and to change lyrics with timestamp seconds from 3 decimal places to 2.

So now I have this wonderful Action group.

You've made me very happy.

A couple of things ...

Regular expression to filter path names with diacritics

That's not finding Chinese characters for me.

When I entered NOT %_path% MATCHES ^[a-zA-Z0-9\W_]*$ the filter worked fine, picking up Motörhead etc.

But when I replaced %_path% with %lyrics%, the filter only found 4 tracks (out of hundreds).

It would be handy to be able to search for Chinese characters, if by any chance you have another solution. But given I'll be running that Mp3tag Action group on all my new lyrics, I don't think I actually need it, so don't worry if it's not straightforward.

I also searched for the most common Chinese characters and after filtering by 的, I found a whole bunch. From there I realised that there were a ton of tracks with

作词 which apparently means lyricist
作曲 composer and
制作人 producer

hence the Replace actions in my screenshot above.

I'd also like to put [lyrics not found] into the %unsyncedlyrics% field of some tracks but I couldn't find a way to do it.

I can put in lyrics not found, just not with the brackets. Any ideas please?

This is what I'm using, with the Format string as: %unsyncedlyrics%lyrics not found

I've tried a few things ...

%unsyncedlyrics%[lyrics not found] returns blank
%unsyncedlyrics%"[lyrics not found]" returns ""
%unsyncedlyrics%"["lyrics not found"]" returns ""

Perhaps you could teach me what I'm doing wrong?

Anyway, thanks a million again. I really appreciate it.
