Chinese Language support using Vugen protocol http/html & web service

Using Loadrunner 12.53 on windows 7  64 bit o/s, Vugen with a multiple protocol for http/html & Web service.  I am trying to update and use "chinese characters" in a soap request that works today using English characters.  When i copy / paste the chinese characters "名" in the request it is sending as "???".    I tried using a paramter but still it converts to non character. 

Any ideas?  I need to process this as it is passed to a converter function and I need to performance test the impact of the process.  

   "<PersonName>"
                           "<GivenName>晨 辰</GivenName>"
                           "<MiddleName>晨  辰</MiddleName>"
                           "<Surname>晨</Surname>"

in replay becomes 

<PersonName><GivenName>hf \xB0\x8F\r</GivenName>

<MiddleName>hf \xB0\x8F\r</MiddleName><Surname>hf \xB0\x8F\r</Surname>

</PersonName>
