is a string using the ISO-8859-1 charset and it is not encoded in UTF-8. That string can contain
characters with a value higher than 127 and may result into an invalid UTF-8 string.

Without knowing what version of ActiveMQ-CPP I can't give you a definite
answer there were issues in the 2.x versions with ASCII values greater
than 127, those have been addressed and should work either in 2.2.6 or
3.0.1.  If you continue to have problems with the latest version of the
client then I'd recommend opening a new Jira issue and attaching a
simple but complete test case that demonstrates the issue.
