Further to the point, the same problem happens with wcDrawImageString
inside xmonad.  I just added \x2192 to the run-or-raise prompt in
XMonadContrib, recompiled, and I get the same garbled output as in
xmobar.  Yet, xterm and emacs display the character fine, using exactly
the same font as I use for xmonad's prompts and for xmobar.
