Sort of, thanks.  After waiting a few seconds, Emacs now displays
three characters, but navigation is hard: it takes a few seconds to
move from character to character (I guess Emacs tries to reload the
missing glyph again and again).

If you tell me how to find out the name of the font Emacs tries to
use, I can try to answer this question.
