Hi, Restlet uses the Representation to define the message and mediate type[1]. Camel-Restlet doesn't support the Representation well, and it just try to turn the bytes into String as a fall back. I just fill a JIRA[2] for it and will commit the fix shortly.
You can work around it by changing the message body into an InputStream and set Content-Type on the message header.
