I thought weʼd fixed these kinds of bugs, but obviously not. Can you
try your test in combination with the following from etc/DEBUG, it
should tell us which font is responsible:

    For X protocol errors related to displaying unusual characters or to
    font-related customizations, try invoking Emacs like this:

      XFT_DEBUG=16 emacs -xrm "emacs.synchronous: true"

    This should produce information from the libXft library which could
    give useful hints regarding font-related problems in that library.

Regards

Robert
