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.


Try using the Character.TCharacter.IsLetter or Character.IsLetter functions
