Encoding is happening while sending parameter from Post request in Jmeter

**Pallawi** ([Bug 63481](https://bz.apache.org/bugzilla//show_bug.cgi?id=63481&redirect=false)):
Hi,
I have a Post request in Jmeter in which, ViewState parameter is passing but value for that parameter is combination of alphabates, number, special characters . so while send that parameter request is encoding the special character for e.g. i have forward slash in paramter so while sending it is converting it to %2F and that leads in failing the request

Solution i have tried is:

uncheck URL Encode check box
UTF-8 in content encoding
for ViewState providing ${__urldecode('${viewState}')} value as Parameter value, which(viewState) i am fetching from previous response
used replace function in Parameter value
So what i am expecting is while sending Post request parameters should not get encoded. Can someone please provide solution
