Right, the hard part is mapping whatever weird string "locale charmap"
chooses to return into one of the encodings our code knows about.

HPUX seems to be just arbitrarily bizarre:

$ LC_ALL=en_US.iso88591 locale charmap
"iso88591.cm"
$ LC_ALL=C.utf8 locale charmap
"utf8.cm"
$

As near as I can tell, the .cm is present in all the possible results;
and why the quotes?

Perhaps we could try to derive a setting from locale charmap, but barf
and require explicit -E if we can't recognize it?
