* o Each disallowed character is converted to UTF-8 as one or more bytes.
* o Any bytes corresponding to a disallowed character are escaped with the URI escaping mechanism (that is, converted to %HH, where HH is the hexadecimal notation of the byte value).
* o The original character is replaced by the resulting character sequence.
* The character '=' (0x3D).
* A globally unique value such as a UUID.
* The character '@' (0x40).
* A valid domain name under the authority of the entity constructing the message.
