Cygwin already generates these unpaired surrogates in filenames, at least
here:
https://github.com/cygwin/cygwin/blob/84dff09aa0d3ad998551e3f91c61dc0534b0b8bf/winsup/cygwin/syscalls.cc#L342-L350

I was looking into ways to automate cleaning up these files, which would
likely be hampered if things like findutils would suddenly start
disallowing me from finding files with these characters in them.
