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

Do you ask this same question elsewhere too?
Just to save the time to search for and post a solution...

I don't quite understand.

I don't have a solution to the Chinese characters conundrum.

In that other thread you kindly helped me find the 3 decimal places files, and I'd found another way so I took the time to spell it out in case it would be useful for anyone else searching in the future.

Then I posted this thread about a separate question.

Then I linked to this thread to you, and you only, just because were were already communicating and you seemed very knowledgable about regex.

I really want to find out how to get rid of the Chinese lines in all my lyrics, but I've searched high and low and cannot find a way. Hence this thread. I only mentioned it to you in in the other thread as I was already writing a post to thank you and just thought I'd add that in.

Anyway, this is why. This is [what I see on my phone's music player]

Can anyone help me on this please? I'll be so grateful.
