Once removed the Adobe Type 1 Symbol font, the problem disappears. The
0x22 "FOR ALL" in the OpenType Symbol font does not preclude Emac
selecting a suitable U+2200 in DejaVu Sans Mono.

In fact, removing all Type 1 fonts fixes all three problems I was
having with font selection:

  - The incorrect display of space for some missing characters (i.e.,
the problem in this thread)
  - The garbage in the startup screen in place of "Meta-x recover-session RET"
  - The screwing of *all* glyphs when visiting HELLO using the default
startup font.

I'll try to debug it over the weekend; perhaps I can find some clue.
