Good morning!
/bin/ls -l cannot handle printable Unicode characters outside the BMP
Example using 'π―'
bash -c 'printf "\U0001D4AF\n"' # MATHEMATICAL SCRIPT CAPITAL T
(yes, our mathematicians want to use THAT as file name)
On Linux:
LC_ALL=en_US.UTF-8 bash -c 't="$(printf "\U0001D4AF\n")" ; touch "$t" "$t$t"'
ls -la

Looks like the Cygwin locale has a problem with non-BMP chars.
find(1) is even worse:
$ find .
.
./ΓΆΓΆΓΆΓΆΓΆΓΆΓΆ
./????
./x??x
The Microsoft Explorer GUI shows the file names correctly, so IMO this
is not a Windows or Win32 API problem.
Slightly different filename problem which may be related or not:
