I've looked on three systems, two Mac's - one is a colleagues, and one is my
wife's which I don't do any funky stuff on. And on my Windows system, I
looked at these in 'all' available fonts I have. Most of the fonts
installed showed empty whitespace, including Arial Unicode MS, Courier New,
Lucida Sans Unicode, and Everson Mono. Some fonts, not many, showed boxes
Do you know which font you used and could you try a few more on Mac? How
does system and application configuration determine which font displays a
character when many fonts are capable?
When you say you think I have a font installed incorrectly on these three
systems, do you mean the font is the problem or the way it's installed is
the problem?

On my Mac they are not white space. It looks like you have a font
installed that (incorrectly IMHO) uses a blank glyph to display them.
