for Java 5. Java 5 is based on unicode 4, which means variable-width encoding.
supplementary character support should be fixed for code that works with char/char
StandardAnalyzer, SimpleAnalyzer, StopAnalyzer, etc should at least be changed so they don't actually remove suppl characters, or modified to look for surrogates and behave correctly.
LowercaseFilter should be modified to lowercase suppl. characters correctly.
CharTokenizer should either be deprecated or changed so that isTokenChar() and normalize() use int.
in all of these cases code should remain optimized for the BMP case, and suppl characters should be the exception, but still work.
