Character documentation

# Character

Character inherits from Object and defines no instance variables. It has no subclasses.

Characters are single extended ASCII characters in the range 0..255.
Character predicate methods (isLetter, etc.) use the PalmOS character functions, so they will work with "extended" characters (characters with value greater than 127).
Characters are not immediate values, but are stored in a special way to save space. See the Pocket Smalltalk whitepaper for details.
