[zeromq-dev] Zproto framesize calculation for UTF-8 in Java

I’m experiencing a buffer overflow when using utf-8 with an zproto/gsl generated message class.

The framesize for strings seems to be calculated based on the number of characters in a string.
Later the bytes of the string are put into a buffer and when the string contains multi byte characters, the buffer overflows.

Has anyone else experienced this behavior?
Or is this behavior intended, i.e. am I using it wrong?
