Forms Enctype and PHP processing

Application/x-www-form-urlencoded encode all characters before sending (default)

Multipart/form-data characters are not encoded. You must use this value when you use a form that contains a file upload control.

The text/plain space is converted to the "+" plus sign, but does not encode special characters.
