It doesn't really make it "less of a hack" since Windows just maps the
glyphs encoded from from F020 to F0FF in the cmap of "Windows Symbol"
fonts to characters x20-xFF in the Windows code page for your locale
(normally "Windows ANSI" if you are in the US or UK). You still type in
non PUA characters, and those non PUA characters are what gets stored in
your files - *not* PUA characters.
