Determine latin characters in cells

@ Fotis
Could you open the attached file and, with the yellow cells, copy > paste special > values?

If you could then post the result we might better know what a Greek version of Excel sees.

Part of the problem so far is if the strings contain spaces, commas, full stops, etc, or even numbers they will be read as "Latin", that is these universal characters will not return CHAR(63).

I have some UDFs for returning Hex/Unicode. They might be adaptable to get a more universal solution to this thread.

[EDIT]
Could you add to this, in say P1, drag down to P255.

Formula:

=CHAR(ROW())

Again Paste Special > Values, the result you get.

Thanks
