Subject [jira] Commented: (LUCENE-1390) add ISOLatinAccentFilter and deprecate ISOLatin1AccentFilter
Date Thu, 04 Dec 2008 02:15:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12653132#action_12653132

Mark Miller commented on LUCENE-1390:
-------------------------------------

Not to be wishy washy, but deprecating is looking better to me. If there is a large outcry,
it can always be revisited before its fully removed. The odds that you will be affected legitimately,
appear pretty low. We can call it out in 3.0 changes, and those that really need it (which
is looking like it would be a weird situation to need it) could maintain their own copy. Seem
reasonable?

> The ISOLatin1AccentFilter is removing accents from accented characters in the ISO Latin
1 character set.
> It does what it does and there is no bug with it.
> It would be nicer, though, if there was a more comprehensive version of this code that
included not just ISO-Latin-1 (ISO-8859-1) but the entire Latin 1 and Latin Extended A unicode
blocks.
> See: http://en.wikipedia.org/wiki/Latin-1_Supplement_unicode_block
> See: http://en.wikipedia.org/wiki/Latin_Extended-A_unicode_block
> That way, all languages using roman characters are covered.
> A new class, ISOLatinAccentFilter is attached. It is intended to supercede ISOLatin1AccentFilter
which should get deprecated.
