Special characters problem

Hi

I use LoadRunner 11.52. I got a problem of delimiters. The delimiters are not parameter delimiters({}) but delimiters such as ",".

My Load tests between LoadRunner and a web server are seemingly successful. But the connections between a web server and a gateway server are failed in the server logs. The problem was a korean character delimiter.

Flow:

LoadRunner ---[successful]---> web server ---[failed]---> gateway server ---[n/a]---> database server

Example:

web_submit_data("ShowData", 
   "Action=https://xxxxxxxxxxx",  
   "Method=POST", 
   "RecContentType=text/html", 
   "Snapshot=txx.inf", 
   "Mode=HTML", 
   ITEMDATA, 
   "paramData", "Value=123?456", ENDITEM, 
   LAST);

The "?" in the 123?456 is originally a korean character delimiter. But LoadRunner sends requests not as the korean character but as the "?" itself.

I replaced the "?" with the korean character itself, unicode and url-encode in the Action.c. Nevertheless all I have done was nothing but a waste of effort.

How can I solve this problem?

Thanks in advance.
