Thank you for suggestion, but still no luck. I've tried both t and nil
to no avail.
That said, for permanent customization in init file, I will need to
specify particular fontset anyway, right?

Admittedly not often, but there are still 2 problems:
1. When I do customize the default face, say in 1 year, and it doesn't
work, how do I find/recall why?
2. The result of (set-fontset-font) will depend on the moment of its
execution relative to application of customization of default face.

This is not the same as "preferred font(s)" would be if Emacs had them.

Obviously the former. Just suppose I only install DejaVu Sans Mono font.
Nothing else. No other fonts at all. How would Emacs behave by default
in such a setup? Now I need to force such behavior in a system where
multiple fonts are installed.

Somehow it still doesn't work for me even for windows-1251, dunno why.
