I have both the Symbola and Aegyptus fonts installed; when I run emacs
with -Q, only the bicycle and bicyclist characters are correctly
displayed, the Egyptian hieroglyph is displayed as a hex box.  But when
I then set the default font (e.g. via the Options menu) to Aegyptus
Regular, all three characters are correctly displayed.  So the installed
Symbola fonts are found by default, but not the installed Aegyptus
fonts.
