No, we should find a good external library that handles that for us.

glibc comes with 'iconv', that should be a good place to start for most
systems.  Probably we should create a wrapper function that just calls
iconv on glibc-based systems, or equivalent on other boxes.

Look at the $LANG environment variable, that's probably a good start on most
systems. The various LC_ environment variables if you want to do more
localization work.
