How to find unicode characters that are not utf8 in VS Code?

Question

I have unicode characters that I can't see, that are not utf8, I need to spot them.

I used the extension Highlight Bad Chars (Kevin Wenger) but it's not sufficient, in particular, I don't know which are these characters and I don't want to have to define them in advance.

How can I do this with VScode ?

Answer 1

Find [^\x00-\x7f] and Check use regular expressions.
