The coding system *is* just a name (AIUI, for Emacs; XEmacs and old
Mule exposed the internal coding system object for reasons I don't
claim to understand).  That name happens to be a symbol, that's all.

I think it would be reasonable for this function to also accept
symbols (and attempt to guess coding systems from their print-names,
if they are not coding system names).  Eg, return 'utf-8 if handed
'utf8 or "UTF8".

Actually, if I recall the thread correctly, normally they won't.
They'll be *MIME* charsets, which correspond to Emacs *coding
systems*.
