Unable to corelate Arabic values in loadrunner (Web\HTTP|HTML)

Hi,

Am working in oracle apps application with Loadrunner 12.50 Version (Web\HTTP|HTML) protocol.
Our application contains Arabic values are passing like dynamic values. We need to correlete the Arabic values and send it to server but here i am facing some issues.

Snapshot of arabic value is going in this format: الاحساء

But we are sending the arabic value in this URL Encode format: %26%231575%3B%26%231604%3B%26%231575%3B%26%231581%3B%26%231587%3B%26%231575%3B%26%231569%3B and our request is failing.

Actually we need to send the arabic value in RAW URL Encode format: %D8%A7%D9%84%D8%A7%D8%AD%D8%B3%D8%A7%D8%A1

In loadrunner or c language do we have any functions to convert URL encode fomat to RAW Encode format, Requesting your help to proceed further.

Regards,
