[ http://jira.jboss.com/jira/browse/JBAS-872?page=history ]
Scott M Stark reassigned JBAS-872:
----------------------------------
Assign To: Alexey Loubyansky (was: Scott M Stark)
> Problem with non-English characters in UTF-8 encoded queries
> ------------------------------------------------------------
>
> Key: JBAS-872
> URL: http://jira.jboss.com/jira/browse/JBAS-872
> Project: JBoss Application Server
> Type: Bug
> Components: CMP service
> Versions: JBossAS-3.2.6 Final
> Reporter: SourceForge User
> Assignee: Alexey Loubyansky
>
>
> SourceForge Submitter: azzazzel .
> I'm resubmitting this issue since the the last time I
> did (see #887491) it was understood wrong,
> closed and marked as "invalid" by "loubyansky" without
> even making the effort to clarify it.
> --------------------------------
> Initial Comment (see #887491 for full text):
> It seems that all characters coded with more than one
> byte (2+ bytes) in UTF-8 encoded queries are
> incorrectly parsed by [EJB/JBoss]QLParser as seen in
> this log fragment:
> [...]
> If I pass parameter like '\u0105' instead of ''
> then it works.
> [...]
> Comment By: Alexey Loubyansky (loubyansky):
> Why is 'ą' supposed to be understood?
> Either you provide unicode content as is (not the
> 'ą' form) or you use unicode escapes as defined in
> the Java
> spec, i.e. '\u'.
> --------------------------------
> I very well know that "ą" is not supposed to be
> understood!
> What I have typed in the <TEXTAREA> was character with
> Unicode code \u0105 also called "LATIN SMALL LETTER A
> WITH OGONEK"
> I guess it was converted to "ą" by SF and I haven't
> even noticed it was!
> I bet if you type Russian characters in <TEXTAREA> they
> would also be displayed in &#XXX; form.
> This subject was discussed previously on JBoss-user
> list and Alexey Loubyansky was also answering my
> e-mails there.
> (See:
> http://www.mail-archive.com/jboss-user@lists.sourceforge.net/msg35226.html)
> I have also contacted Alexey Loubyansky and Dain
> Sundstrom since they are mentioned to be the authors of
> "JBossQLParser.jjt" and "EJBQLParser.jjt".
> Alexey didn't answer, while Dain stated he does not
> work for JBoss any more.
> I was asked to open a bug report by Heiko Rupp on
> jboss-user list!
> Now once again to make it clear:
> I do not enter in my queries characters in the form
> "ą" but naturally in UTF-8 encoding (as they are
> typed)!
> It does not work! It is incorrectly parsed! I believe
> it is because parser expects 1 byte long character
> (\u0105 has two bytes in UTF-8).
> As I said before setting "JAVA_UNICODE_ESCAPE = false"
> in "JBossQLParser.jjt" and "EJBQLParser.jjt" solves the
> problem!
> More specifically it causes that parser understands
> UTF-8 but does not understand Unicode escaped
> characters (in the form \uXXXX).
> I don't know how to set it in order to understand both!
> Can I please ask you, to have another look on this!
> Please contact me if you need more information on this
> subject!
