There are characters that consist of more than one codepoint - composite
versions of characters for accents. See
https://unicode-table.com/en/blocks/combining-diacritical-marks/
I think the best way is to scan the codepoints looking for
codePointToNum values that are 0-31 (exclude tab and cr/lfs if you like)
and 127 (DEL). There may be some others in the 128-255 range that are
not printable. I forget off the top of my head.

Hi folks, hope everyone is well.
Would I be right in thinking if codepoint count > the number of chars in a text
string, then it probably contains invisible characters?
Or would I need to search through Hex to check?
Or something much easier and cleverer that I hadn’t even considered. Because
that’s what this list and working with Livecode is like.
