--- Comment #9 from Werner Lemberg wl@gnu.org --- I don't have time to fix all these things, sorry.
Note that I touched neither the cmaps nor the glyphs in `fonts-courier.ttf' (except the `.notdef' outline glyph which has now a sensible shape) – warnings about missing characters must have been there earlier also.
