    Because UTF-7 encodes certain plain-ASCII characters, such as the
    greater-than sign > which is used for quoting. It must encode at least
    one (the plus sign) as an escape character, and some others are encoded
    so they will pass safely through mail.

    Mail agents that cannot correctly render my UTF-7-encoded message will
    show sequences beginning with +AC or +AD in place of certain ASCII
