Robert Muir updated LUCENE-2942:
--------------------------------
Attachment: LUCENE-2942.patch
here's a patch, i only converted the really safe stuff over: toString()s and
assertions and some tools in contrib/misc such as HighFreqTerms.
> toString() methods on term/queries/etc are wrong: assume utf-8 encoded bytes.

> Key: LUCENE-2942
> URL: https://issues.apache.org/jira/browse/LUCENE-2942
> Project: Lucene - Java
> Issue Type: Bug
> Affects Versions: 4.0
> Reporter: Robert Muir

>
> In Lucene's trunk, a Term is just a Bytesref.
> In a lot of cases this is a UTF-8 encoded string, but in some cases its not
> (e.g. collation fields).
> The problem is that the toString methods all currently call utf8ToString().
> This is wrong, though from a practical point of view i think just printing
> the bytes won't be very helpful for debugging most cases where the bytes
> really are utf-8 encoded.
> So i think in these cases we should use the following technique: if the bytes
> are a valid utf-8 sequence, use BytesRef.utf8tostring(), otherwise just print
> the bytes: BytesRef.toString()
> its no problem for performance because toString is only for debugging anyway.
