Well, my man page formatter has a flag for Latin-1 encodings, but
nothing else.  When Netscape works, it displays things in Latin-1.  So
at least this Unix user would find Latin-1 more familiar and convenient than
anything else.

So it's not a de facto standard, but an actual specified standard.  All
the more reason to go with Latin-1, it would seem.

Sure there are systems that do it wrong, but how are we to detect which
ones do it wrong and which ones do it right?  Should we really display
correct pages wrong, just so that we can display shabby pages correctly?

Surely, we'd still do isoToSqueak by default when we download a web
page or an email.  If Squeak uses Latin-1 internally, then it's an
identity translation and we display correct pages/emails perfectly.  If
Squeak uses something else, then we are going to lose something.  And
if the page is incorrect, it's going to look bad no matter which way we

Given all this, Latin-1 (or this ISO 10646 thing) seems like the way to go
for compatibility with the Internet.  Perhaps have *overrides* for bad
pages/emails, but surely we need to at least support correct ones.
