Newline character in post request

I want to send new-line-character as part of a value of a post request (text)varia开发者_Go百科ble. I am using wget to fire the request. How do I code that ?

According to the W3C spec, you encode a line break as %0D%0A in the x-www-form-urlencoded format -- which is what you hand to the --post-data option to wget.
