Subject [jira] Commented: (LUCENE-1793) remove custom encoding support in Greek/Russian Analyzers
Date Sun, 09 Aug 2009 17:54:14 GMT

Robert Muir commented on LUCENE-1793:
-------------------------------------

good idea, curious what other encodings you had in mind?. I only thought of BOCU because it
maintains binary sort order, so it makes sense for an index...

and it looks like there could be a possible performance benefit to something like these as
well over UTF-8 (at least for certain languages): http://unicode.org/notes/tn6/#Performance

> The Greek and Russian analyzers support custom encodings such as KOI-8, they define things
like Lowercase and tokenization for these.
> I think that analyzers should support unicode and that conversion/handling of other charsets
belongs somewhere else. 
> I would like to deprecate/remove the support for these other encodings.
