Check if character is letter in Delphi (Unicode)
Are there pre-defined charsets in Delphi, to check if a character is a letter?
In Cocoa I use something like
if ([[NSCharacterSet whitespaceCharacterSet] characterIsMember:character])
I know I can do in Delphi
if c in ['A'..'Z'] then
but will this cover foreign accentuated characters like Á, À, Ú, É, ....?
What would be the most efficient way to check this in Delphi. I need to check if a string is fully composed with letters.
