Topic selector with non ASCII characters
Hi,
we are using topic messages to sent messages from one user to another. Our
program subscribe a durable consumer with selector "UserName='<user>'" and
sent a message with the property "UserName" and value "<user>".
All works fine, when <user> contains only ASCII characters. When <user>
contains non ASCII characters like äöüßé, the message is not sent to the
consumer.
I have looked in the data files and everything looks fine.
We are using ActiveMQ 5.2.
Thank you for help,
Peter

Care to submit a patch for the correction so that it gets into the
next ActiveMQ-CPP client release?

Ok, i have found, that the problem is in the ActiveMQ-C++-Client. The client
do not handle the encoding correct. I have correct it. Now it's works fine.

According to the JMS spec, section 3.8.1.1 Message Selector Syntax:
A string literal is enclosed in single quotes, with an included single quote
represented by doubled single quote; for example, ‘literal’ and ‘literal’’s’.
Like Java String literals, these use the Unicode character encoding.
Just an idea, have you tried using the Unicode characters instead of
ASCII?
