Excellent catch.
What about the '/' as in U/UN/N U/UN/N for a UK postal code?
Thanks, DW.

For string masks this does not exist. Therefore I suggest that
we introduce this concept for strings. The problem is what character to
use? I suggest the following:
X any char mandatory . Any char optional
U Uppercase mandatory ^ Uppercase optional
L Lowercase mandatory _ Lowercase optional
What doe you think?
