Java class with unicode code range specifications

Is ther开发者_JAVA技巧e a class where the code ranges of unicode is defined as an enumeration or as constants? It's a very simple class where the code range specification (can be found anywhere like this for example: http://www.ssec.wisc.edu/~tomw/java/unicode.html) is put into a class, but this is a lot of boring work and I wish someone else has done it before!

See java.lang.Character.UnicodeBlock.
