Most Forms Processors will automatically convert data from pure ASCII Text to URL Encoded data. URL Encode takes ASCII characters (Non Standard Alphabet) and translates them into their Hexadecimal equivalent and places a % ahead of them. A comma (,) translates into %2C and a colon (:) translates into %3A
