I tried to make a formula which just have to return TRUE | FALSE if a cell contains one or more non-latin characters and tried something like this, but failed - it's always TRUE (found nothing here):
=REGEXMATCH(B2; "[[:^alpha:]]+")
Some examples of data:
- daocao@yahoo.com - there are no non-latin characters
- huynhbaoquóqdq@gmail.com - there is a non-latin character
What is wrong with it?
