Thanks for this note (and upthread). I didn't know Emacs settled on
this strategy. It could fit in as a new "conversion strategy" (see
Encoding in the manual).
I think this feature will probably slip for 2.2.0 for lack of time,
though. When someone does go to look at it, this thread is a useful
resource, or parts of it anyway :) I especially appreciated the
tradeoffs between surrogates and strange UTF-8 hacks.
