What operating system are you running? Windows 9x? Even there
I don't know why Unicode would generate a disk space warning; does it
default to UCS-4 or something silly like that? Windows NT 4.x, 2000, XP,
and 2003 all use UTF-8 natively. Disk space is not a big concern.
Anyway, Unicode isn't a piece of software you download and install.
It's a specification to which other software conforms (or, more often,
doesn't conform, but that situation is improving). All you need in
order to display Unicode 4.x glyphs is a font that includes the desired
glyphs and their Unicode 4.x mappings. You don't need anything more
from the word processor or operating system than what is required for
