Yesterday I had a different emacs problem (utf-8 pasted
into an emacs -nw buffer was corrupted when preceded by an
ESC-q command, for any q), and debugging showed that the problem
was not with emacs but with luit, a layer that sits between
xterm and emacs -nw. Since luit parses its input and recognizes
escape sequences, it is in a state where it truncates UTF-8
when it thinks it is reading an ISO 2022 escape sequence.

OK - so emacs -nw under luit has some strange corruption issues.

Returning to this old problem, I now conjecture that also that was
caused by luit. It is somewhat difficult to reproduce, but a moment ago
I did reproduce it once with emacs -nw under luit, and saw no problems
without luit.

Perhaps the problem has been solved and no emacs fixes are required.
