    This algorithm is described in RFC 2231, but is barely touched upon except
    for mentioning bytes can be represented as their octet values (e.g. %20 for
    the SPACE character).

The tests here focus on how to use that representation to always generate text
    which matches RFC 2045's definition of "token".
