You can try the Gremlins extension which I found better than Highlight Bad Chars (Kevin Wenger) (at least, Gremlins worked out of the box; I couldn't get Highlight Bad Chars to highlight anything).

You could try the AttributeEncoder with “Replace invalid characters”=Yes to transform the string to e.g. Latin-1 (or whatever you require), then compare the string before and after so see if any extended Unicode characters where replaced/removed.

r/Unicode on Reddit: Identifying Unicode characters used in an image
March 27, 2022 -
I came across the following Unicode character string, but I essentially only have access to the string in the form of an image.
https://i.imgur.com/QSGMQM7.png
My goal is to figure out which characters are being used above so that I can transcribe the entire string into text.
Does anyone happen to know which characters are being used above for the icons at the beginning and end? I'm aware that the font being used may complicate things somewhat.
If not, are there any OCR applications, or other types of software available that can do this type of identification? Searching Unicode OCR unforunately just bring me to Unicode's OCR block.
