You mean Code 2000? My copy of Code 2001 (Version 0.913) does not 
have D with underdot (0x1E0C). Or a new version is available? Anyway 
personally I prefer TITUS Cyberbit Basic or Thryomanes.

Today, I cannot reproduce the difference between the rendering of OW 
4.0.6 and that of OW 4.1 sp. 24. This makes me crazy because I had 
tested and confirmed this during a week repeatedly before I posted 
the previous message. Has this something to do with the fonts 
installed in my Mac? I add or remove fonts frequently...

Yes. It seems that quitting and restarting OW is needed.

One more mystery. If you have a font which contains D with underdot 
in Bold style installed in your Mac, OW renders the character almost 
correctly, even if Times and Monaco are selected in OW's Font 
Prefereces. I say almost correctly because the style is not respected 
for uncommon characters which are not contained in the preferred 
font, so, for example, n with underdot in Regular style in some 
passage is rendered in Italic style. Is this normal with Font 
substitution?
