another utf-8 decoder

[Thien-Thi Nguyen]

Greetings earthlings,

Just a quick message to signal that ttn-do 355 has Yet Another
UTF-8 reader.  A nice feature that others (that i've briefly
researched) do not have is that the byte stream is exposable.
This means you can write a reader for another encoding (or use
another UTF-8 reader instance) and have them cooperate by passing
around the byte stream.

Other niceties: input type muxing, built-in skip and resync,
separation of UCS check from UTF-8 proper, complete example in
documentation.

For more info, see <http://www.gnuvola.org/software/ttn-do/>.
