supplementary character handling
--------------------------------

                 Key: LUCENE-1689
                 URL: https://issues.apache.org/jira/browse/LUCENE-1689
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Robert Muir
            Priority: Minor


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.
