Should, yes, once we get our ducks in a row.

Pretty much like the 8859-x mess in general.  Not a pretty sight.

So I gather...

What are you supposed to do in a pure VMS system, if you can't pass the
output of nl_langinfo(CODESET) to iconv?

I can see writing a trivial tds_get_iconv_ascii_name() that returned the
appropriate string in the absence of locale_charset().

I'm not going to dignify that with a reply.  Not that I could.
