Timothy A. Bish commented on AMQCPP-751:
----------------------------------------
As this issue continues to be a client issue I am moving to the CMS client
where a fix would need to be made to bring it into full compliance with other
Openwire clients in how multibyte strings are encoded.
> Non-UTF-8 messages containing special characters are not supported

> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Reporter: Liviu Citu
> Priority: Major
>
> When a text message non-UTF-8 (ISO-8859-15) containing special characters is
> sent from ActiveMQ CPP client to Artemis, an exception
> "java.io.UTFDataFormatException" is seen in Artemis server log.
> Although the exception is thrown as a warning, the message gets rejected by
> the server.

>
> This is a regression compared with ActiveMQ Classic which does not have this
> issue.
> Does Artemis support non-UTF-8 encoding? Do we need now to encode all
> messages to UTF-8 before sending them to the server? Similarly to decode them
> upon receiving?
> This will cause some problems on our end because:
> * we have many clients already using the ActiveMQ classic and migrating them
> to Artemis will cause issues when migrating KahaDB to Artemis because all the
> messages have to be encoded to UTF-8 otherwise they will not work in Artemis
> * encoding/decoding every message will impact the overall performance. We
> have applications handling thousands of messages every day and conversion of
> these messages will increase the time spent during communication with JMS
> broker
