There is no class for single characters. There is a unichar type and I believe what you are looking for is: http://www.gnustep.org/resources/documentation/Developer/Base/Reference/index.html [http://tinyurl.com/5wm8kv] http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Classes/NSCharacterSet_Class/Reference/Reference.html [http://tinyurl.com/6754gg] which provide -characterIsMember: for special character sets.
