I'm a bit confused as to what char you are trying to access/use, as
U+F020 is in the Private Use area (PUA)
Since it's in the PUA, it seems its meaning could differ by
application/OS/User, no?
I.e. have no set definition
I mean you can use it in Cygwin to represent some character not usually
permitted in
a DOS/Win filename (like :/\, etc.), but it wouldn't have the same
meaning then
in Windows though.? Isn't Private Use area application specific so an
application can
create and use its own symbol set -- even though it wouldn't be portable
to another application.
So if you create a character in Cygwin that maps to that area -- how
would you expect Windows to
know that the character is and how treat it?
I think characters in the PUA range are used to allow Cygwin filenames
to contain colon, slashes
and quotes -- so one wouldn't want Windows to understand the cygwin
intent or it would defeat
the purpose of using custom characters to represent filenames that are
legal under POSIX but not
under Windows.
