In brief, UTF-7 attempts to represent unicode in a 7bit character set,
this means some characters from a 7bit set need to be used for control
sequences and have to be encoded. In practice only "+" really has to
be, but all the 'optional direct characters' might be, see
<http://en.wikipedia.org/wiki/UTF-7>. Contrast UTF-8 where all
low-byte characters are 'un-encoded' and only high byte characters are
used in the multi-byte codes.

Haven't used it in a while, will investigate later.
