Works fine for me, except that apparently zsh doesn't support UTF-16
surrogate pairs, so they're shown as separate codepoints:
"<d83d><de3b>". Line editing works fine though.

Result:
zsh: command not found: \ud83d\ude3b

So, more info needed: please see http://cygwin.com/problems.html, in
particular: "Run cygcheck -s -v -r > cygcheck.out and include that
file as an attachment in your report."

Also, does the CPU usage shoot up? And what's the output of 'ps' (in a
separate window, obviously)?

(Note besides: bash actually displays the cat character, but treats it
as if it was two characters, so line editing goes wrong with the
cursor wandering off the line and that sort of thing. Surrogate pairs
do work properly in vim, emacs and mined.)
