[OpenSIPS-Users] AVP + rest_post with utf-8 values

[Liviu Chircu]

Well, as Linus nicely put it: "Talk is cheap. Show me the code". If you 
take a look at the hex dump, notice that the "..." display characters 
are actually "e7928e", twice. I haven't double-checked, but I have a 
pretty good feeling that they represent our Chinese symbol. Which should 
mean that everything is okay on the OpenSIPS side.
