Hi, Have uploaded a new update (http://issues.apache.org/activemq/browse/AMQ-656) for the C++ client which adds encoding support. It now contains an encoding framework with a default encoder that encodes to/from extended ASCII and modified UTF-8 as used in Java. The encoder can easily be replaced or turned off should you want to supply your own encoding. Also, a readme file has been added that documents the URI parameters and build commands.
Tested on Windows XP (SP2), RedHat Enterprise Linux 4 and Mac OS X 10.4 with ActiveMQ broker 4.0 (pre-final). Regards, Mats
