How to find all non-displaying characters (hieroglyphs) in mysql database?

Question

PHP

Cyrillic characters got into the table, designed only for the Latin alphabet.
Can any query display all the lines where they occur?
The need is to find these lines, and not to somehow correct their display.
These lines will be further processed in a different way.
The option with [a-z] is not suitable, because in base these characters are displayed by krakozyabry and sootv. so mysql doesn't find anything.
Thank you!
