Re: Can not stat file with utf char U+F020

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.
