(Late for this thread.)
ICU4J comes with its own "UCharacter" class that provides Unicode 3.1.1 properties for all code points, using int for the single-character type.
A class library can of course not fix the problem of string literals with \u - we either use two \u's for surrogate pairs or an unescape function (I think on the UTF16 class) that understands \U.
