If you have additional fonts installed, beyond those which came with
Windows out of the box, Emacs will examine them even in "emacs -Q".
When Emacs needs to find a font for some character, it enumerates all
the fonts installed on the system, and then examines them to find the
one that can actually display the character.  This happens even
without non-default customizations.
