RE: problem with non latin characters in the query

[PERRIN GOURON Olivier <ol...@xml-ais.com>]

Hello,

I am using Lucene to index UTF-16 and UTF-8 files . Those files are
trans-encoded to the right format so that they can be indexable with Lucene.
The index is searched through with queries made from an UTF-16 file.
Everything works fine as long my query file contains latin characters (even
specific french chars such as éàèêoe...)
Problems occur when the UTF-16 query file  contains not latin characters. I
have tried russian characters, such as ?, which is \u0418, but Lucene sends
me this error:

	Exception in thread "main"
org.apache.lucene.queryParser.TokenMgrError: Lexical
	error at line 1, column 8.  Encountered: "\u0018" (24), after : ""

Seems that the queryParser doesn't use the right code for ?... I have tried
greek, and I does the same.
Is it due to the analyser? I don't think so since I changed my
StandardAnalyser for the FrenchAnalyser, and it still behaves the same
to the query parser?...

Another problem that gives exactly the same error message occurs when a
world in my query starts whith a local character (éàèêoe...). This is weird,
since local characters do not trigger errors when they are in the middle of
the world.

Have you ever met this problem? I would appreciate your help and advices

Thanks for your consideration
