A question mark is a sign of a bad conversion from Unicode (to a code page that did not contain the character). This would likely happen on the Mac too rather than the Last Resort font, wouldn't it?
No, it wouldn't. A "not a character" glyph is displayed in the Last Resort font.
On Windows, the "cannot find a font for it" situation is the NULL glyph.
