Font substitution does not work properly with 4.1 beta

[Brian Covey]

Ok...
Behavior on this bug is even stranger. I now cannot duplicate what I 
saw, but something weird is going on here, and I'd appreciate it if 
someone out there can try to duplicate this, so I know I'm not insane.

OmniWeb 4.1b1, with the Code2001 font 
(<http://home.att.net/~jameskass/code2001.htm>) installed and set up as 
default proportional font in Display preferences.

Went to the page kino mentions in his message:
<http://www.bekkoame.ne.jp/~n-iyanag/articles/dakini/dakini1.html>

The first couple of times I loaded this page, whether in OmniWeb 4.1 or 
4.0.6, I saw the D+underdot character rendered with the Code2001 glyph. 
I am sure of this.

At some point in my futzing around, I switched the default font in 
OmniWeb to
"Brush Script MT". At that point the page started rendering all the 
D+underdot characters in the LastResort font. 
(<http://developer.apple.com/fonts/LastResort/LastResort.html>)

 From this point on, even after I switched the default font back to 
Code2001, we would always render the D+underdot characters on that page 
in the LastResort glyph. Even after a reboot. Which seems to match 
Kino's behavior, except I have never seen the two versions of OmniWeb 
get out of synch; either they both rendered it, or they both didn't.

So, someone out there with too much time on his or her hands want to try 
to duplicate this sequence of events?

Install the code2001 font, and make it the default OmniWeb display font.
Go to <http://www.bekkoame.ne.jp/~n-iyanag/articles/dakini/dakini1.html>
Are you seeing the d+underdots rendered in code2001?

Now switch the default to a font that doesn't have a bold typeface and 
reload the page; glyph should now render in LastResort.

If you switch the default back to Code2001 and reload the page yet 
again, is it still rendering in LastResort? Or am I completely off my 
rocker?
