[jira] Commented: (LUCENE-1793) remove custom encoding support in Greek/Russian Analyzers

["Robert Muir (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-1793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741093#action_12741093 ] 

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

I am guessing the rationale for the current code is to try to reduce index size? (since these languages are double-byte encoded in Unicode).

If this is the concern, then I think a better solution would be to integrate some form of unicode compression (i.e. BOCU-1) into lucene, rather than try to deal with legacy character sets in this way.

> 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.
