Probably not even notice, since charset & locale are two different
concepts, and I don't think Solaris has ever shipped a US-ASCII
locale, since it doesn't match the locale name scheme - it would
be something like en_US.ASCII to include region, language & charset.

On Solaris, "locale -a" does not list US-ASCII, and both of these
just show fallback to C:
	env LANG="US-ASCII" locale
	env LANG="bob" locale
