Sorry for the late response; I see you reproduced the case meanwhile -
anyway, here is a test case, to be used with gcc or just with cat:
/* print U+20000 ð €€ */
int main () {
printf ("<U+20000> is <ð €€>\n");
}
where you could enter the character in mined with Control-V #20000 Enter :)
About non-UTF-8, I tried to test in Big5, using character 0x8750 which is U+242BF,
and the test suggests it's OK (in cygwin console, mintty, and rxvt-unicode);
however, that may not be significant since although its Unicode code
point is non-BMP, the Big5 character is only 16 bits and Windows,
having supported CJK before Unicode, probably doesn't handle this via Unicode.
I also tried to test eucJP, but that doesn't seem to work at all and mintty crashes...
See my other comment below, please.

The problem used to be in mintty as well until I pointed it out and
Andy was so ambitious to find a workaround - maybe he could supply a
code snipplet which would fix this in the cygwin console too, despite
the bug origin being in the Windows API...

You would have to test this with rxvt-unicode (urxvt in cygwin)
where the test case passes (one box). (Not very relevant maybe,
if reports are true that rxvt is not maintained anymore.)

I was assuming that, like for mintty, the fault was not in the cygwin domain,
however, as there is a workaround, I thought it would be nice for the cygwin
console as well.
Kind regards,
