Michael McCandless commented on LUCENE-1689: -------------------------------------------- That sounds right. We would also deprecate the char based methods? And note that in 3.0 we'll remove them, and make the int-based methods abstract? And, then fix CharTokenizer to properly handle the extended chars? We may need to use reflection to see if the current subclass "wants" chars or ints, and fallback to the old (current) char processing if it's a subclass that doesn't define the int-based methods. > 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 > Fix For: 3.1 > > Attachments: LUCENE-1689_lowercase_example.txt, > testCurrentBehavior.txt > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
