This one looks completely unrelated to the one above.

What change exactly? What's the original filename here, and how does
it change unexpectedly in terms of POSIX/Cygwin operations? And,
importantly, what's the locale setting?

In a UTF-8 locale at least, there doesn't appear to be a problem with
filename transparency here:

$ echo bla >$'\201=C3=90\201=C3=90\201=C3=90\201=C3=9002ABFx'
$ ls --quoting-style=3Descape
\201=C3=90\201=C3=90\201=C3=90\201=C3=9002ABFx
$ cat $'\201=C3=90\201=C3=90\201=C3=90\201=C3=9002ABFx'
bla
$ rm $'\201=C3=90\201=C3=90\201=C3=90\201=C3=9002ABFx'
