Right, 332 not being able to be converted to a byte makes sense to me now,
and I suppose converting it to UTF-8 resulting in 197, 140 makes sense now
too (it will make more sense when I read further about what UTF-8 does for
characters outside of the ASCII set).  But yeah, I'm still not sure why the
document that says it was encoded in UTF-8 ended up being in UTF-16 (or

Anyway, I really appreciate the help.  I've never really had to think about
what was happening behind the scenes with my strings, but now I've got a
pretty good understanding of how erlang deals with them.
