I'd hope so!  If it got put in straight like that, I'm sure I'd have lots to
moan about.

I'm really not sure, I've just got a problem I want to solve :-)  It may
need to be constantly firing for each glyph so I can construct a list of
what I need to get.

Changing font-family should probably have it fire again, unless there's an
alternative idea where it fires once for any missing glyph and then which
glyphs in the document have failed can be obtained from another property.

Well, with getBBox we can sort of infer it now, so they could have a hack
approach, but I agree it could be problematical.
