The code_converter component I mentioned doesn't use streams either. But it can
be used to adapt streams -- to turn a narrow character stream into a wide
character stream or vice versa.

We've already discussed the tradeoffs between using iterators or objects with a
socket-like interface to perform filtering:

It is crucial to support codecvts, since this is how the C++ standard libraries
encapsulates code conversion. If you don't allow for a user-supplied codecvt,
you can't reuse the large number that have already been written, such as the
dozens that come with the Dinkumware CoreX library.
