There's no (good) solution from inside Cygwin.

Keep in mind that the Unicode area from U+E000 up to U+F8FF is called
"Private Use Area".  So none of the chars are mapped into any
singlebyte, doublebyte, or multibyte charset.  Typically we don't expect
that filenames contain any of these chars, and we're only using a very
small subset of them for our own, dubious purposes anyway:

While this patch would have fixed your problem, a later followup patch
broke your usage of U+F020 (space replacement) and, FWIW, of U+F02E
(dot replacement) again:

This was done to accomodate filesystems implementing the idiotic
approach to support only DOS filenames, i. e., not allowing leading or
trailing spaces and not allowing trailing dots.  These are Netapp and
Novell Netware filesystems.  See the last paragraph of

https://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars

Any chance you can just rename the files?
