Be careful.  This alias has caused Emacs some amount of pain, as
binary data escapes into contexts (such as Universal Newline
processing) where it gets interpreted as character data.  We've also
had some problems in codec implementation, because latin1 and (eg)
latin9 have some differences in semantics other than changing the
coded character set for the GR register---controls are treated
differently, for example, because they _are_ binary (alias latin1)
octets, but not in the range of the latin9 code.

I won't go so far as to say it won't work, but it will require careful
