It's not as simple as that.

To some extent. See below.

A Unicode font wouldn't have helped you there. The "old" way to provide UTF-8
compatibility requires Apple's Text Encoding Converter, which maps characters to
*different* fonts. So you cannot use just one Unicode font, but instead you need to
install all kinds of fonts, and even then you won't
be able to view all Unicode characters, because some blocks don't have a corresponding
representation in Apple's old script system. One example for this is the Extended
Greek block. AFAIK you cannot get that with the TEC.
However, 8.5 and above actually contain ATSUI, the Apple Typography Services for
Unicode Imaging. Those can read all kinds of font formats, including fonts like
Microsoft's Arial Unicode. But that's only one half of
the equation. This fine API doesn't do you any good without applications that support
it. Unfortunately the only mainstream application that seems to do so (I don't know
for sure) is Adobe InDesign 1.5
Mac OS 9.1 comes with a small word processor called WorldText that supports
ATSUI... it's a first step. Here's hoping for the Carbon (or Cocoa?) release of
Microsoft Office...
