> 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[]
> For example:
> 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.
