Sure looks like a bug. Seems unicode characters > U+FFFF trip up
something. On qt (under win7/gp50pl1) I get three question marks in a
black diamond in the plot, and an open square in labels. (i haven't
found a font that actually has that character)

wxt puts nothing in the plot, and a "missing" character (square with
four "0"s in it) in a huge font (fs 60 or so) in labels. I guess the
huge font is another bug triggered by the same thing (probably a bug in
pango and/or because the symbol is not in the font?).
