Steven Rowe commented on LUCENE-1390: ------------------------------------- bq. It would be good to clarify how the goals of this issue differ from LUCENE-1343 ... as an outside observer they seem to be the same thing LUCENE-1343 depends on either Java 6 or an ICU jar. Java 5 support (much less Java 6 support) is still a ways off, and core Lucene can't have external dependencies. IMO, this issue intends to provide *core* Lucene support for folding a wider set of accented characters to ASCII. In a moment I'll attach a patch that, in addition to the larger set of accented characters to be folded that Andi has provided, folds all Unicode characters I could find to their ASCII equivalents. > add ISOLatinAccentFilter and deprecate ISOLatin1AccentFilter > ------------------------------------------------------------ > > Key: LUCENE-1390 > URL: https://issues.apache.org/jira/browse/LUCENE-1390 > Project: Lucene - Java > Issue Type: Improvement > Components: Analysis > Environment: any > Reporter: Andi Vajda > Priority: Minor > Fix For: 2.9 > > Attachments: ISOLatinAccentFilter.java > > > 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. -- 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: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
