Availability: OpenStep
Returns a character set containing letters,

"letters" includes all alphabetic as well as
Chinese characters, etc..
+ (id)
capitalizedLetterCharacterSet;

Returns a character set containing letters in the
unicode Titlecase category.
+ (id)
characterSetWithBitmapRepresentation: (
NSData*)data;
Availability: OpenStep
Returns a character set containing characters as
encoded in the data object (8192 bytes)
+ (id)
characterSetWithCharactersInString: (
NSString*)aString;
Availability: OpenStep

Each bit
set in the bitmap represents the fact that a character
at that position in the unicode base plane exists in the
characterset.
File must have extension
" .bitmap ". To get around this load the
file into data yourself and use [NSCharacterSet
-characterSetWithBitmapRepresentation].
