Subject [jira] Created: (LUCENE-2019) map unicode process-internal codepoints to replacement character
Date Thu, 29 Oct 2009 18:19:59 GMT
map unicode process-internal codepoints to replacement character
----------------------------------------------------------------

                 Key: LUCENE-2019
                 URL: https://issues.apache.org/jira/browse/LUCENE-2019
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
            Reporter: Robert Muir
            Priority: Minor


A spinoff from LUCENE-2016.

There are several process-internal codepoints in unicode, we should not store these in the
index.
Instead they should be mapped to replacement character (U+FFFD), so they can be used process-internally.

An example of this is how Lucene Java currently uses U+FFFF process-internally, it can't be
in the index or will cause problems.
