Ability to decode/encode a single character from/to an octet vector.

[tmccombs]

In some situations it would be nice to be able to decode a single character form a position in a vector, or encode a single character into a vector.

Do you mean something like cffi:lisp-string-to-foreign where the user can specify both the source and target indices?

Not exactly more like

(decode-character #(195 164 195 173 99 195 176) :start 0)
=> (values #\ë 2)

I guess encoding a single character is kind of weird though, since it may return more than one octet. I just put that in for symmetry.
