GNOME 2.10, Yelp 2.10.0, and Firefox 1.5.0.6

[Albert Chin <gnome-doc-devel-list mlists thewrittenword com>]

We've built GNOME 2.10 from source with Yelp 2.10.0 and Firefox
1.5.0.6. We're having a problem where a character isn't being
displayed with the font we've selected and thus the hex sequence is
being displayed in a box. A screenshot is available at:
  ftp://support.thewrittenword.com/outgoing/yelp-2.10.0.png

This hex box doesn't occur if we use Firefox 1.0.8. I know we're
running an old version of GNOME and Yelp. We tried Yelp 2.12.2 but it
exhibits the same behavior.

We're using Bitstream Vera Sans Roman for the variable width font and
Bitstream Vera Sans Mono Roman for the fixed width font.

Any ideas?
