If the source supports Unicode, it should do UTF-8 as well. So, you 
would write

    if C = "±" then ...

where C is String.

Yes, but you need no Wide_Wide to get an integer value and if your 
objective is Unicode categorization, that is too complicated for manual 
comparisons. Use a library function [generated from UnicodeData.txt] 
instead.
