Thanks, I was thinking along these lines indeed. The problem is I can't
figure how exactly do I do it, provided the DejaVu Sans Mono is the font
currently being set through M-x customize-face RET default, and I don't
want to loose the ability to change this way the (only) font I'd like to
use.
I mean, it looks like I need to modify fontset-auto1, as M-x
describe-fontset RET shows:
Fontset: -PfEd-DejaVu Sans Mono-normal-normal-normal-*-23-*-*-*-m-0-fontset-auto1
[...]
and after some more digging, I finally tried:
(set-fontset-font "fontset-auto1" 'windows-1251
(font-xlfd-name (face-attribute 'default :font))
which evaluates to:
"-PfEd-DejaVu Sans Mono-normal-normal-normal-*-23-*-*-*-m-0-iso10646-1"
but doesn't seem to have any visible effect. And even if that worked, it
wouldn't immediately pick subsequent customization of the default face
anyway?
What do I miss?

Maybe I should be able to express exactly this by specifying, say,
"preferred font" for a fontset? I mean: "use this font, unless there is
no suitable glyph, in which case turn back to the fancy methods of
considering charsets".
Actually, I probably do want to use only this font (and have empty
rectangles or some such in case of missed glyphs). I mean some way to
force Emacs to behave as if this font is the only available font in the
entire system. Still no simple way?
