As some may recall, I'm running the original version of Windows 95 --
not even Rev A. That would seem to imply a very low level of Unicode
capability. But I also have IE 5.5 and OE 5.5, which means I have
UniScribe. So I was surprised and delighted to find that I can use the
Windows clipboard to read and write Unicode text, using the
CF_UNICODETEXT type.

Now I have a mini-application that can share Unicode text with SC UniPad
(which of course works on plain Windows 95 even without UniScribe).

So to build on what Peter said, when answering the seemingly simple
question "Does system Q support Unicode?" you need to define both

(a) "system Q" -- different revisions or configurations might have
different Unicode capabilities

and

(b) "support Unicode" -- does that mean bidi, combining marks,
contextual glyph shaping, UTF-8, or simply the ability to display a
precomposed lowercase a with macron?
