gnus is a full-screen terminal newsreader add-on for Emacs:

  http://www.gnus.org/

Presumably it uses bold fonts.  (I wouldn’t know, I cannot Emacs.)

I think the vttest program I pointed to in my other response is more enlightening.

By the way, while going through menu item 2 of vttest to produce the screen shot I posted, I noticed that its notion of “last line” appears to be line 24.  Is it a weakness of MinTTY, vttest, or the VT-whatever protocol that it can’t tell that my MinTTY window is 60 lines high?

If you open the Fonts control panel, in the default Large Icons view, do you see all four variants of Deja Vu Sans Mono stacked together?

I ask because it is possible that the fonts weren’t constructed in a way that lets Windows understand that these four separate font files differ only in weight.  Since this font family doesn’t use the traditional Regular / Bold / Italic / Bold Italic scheme, it is possible that some software wouldn’t know how to move between weights and styles automatically.

There’s a lot of naive font handling code out in the world which only believes in those four variants.
