------------------------------------------------------------

                 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


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.
