Not sure why Emacs on your system displays the former when you request the latter, but at least it's the same letter. Perhaps the font driver substitutes one for the other? > > How is this strange character displayed, eventually?

Math fonts are notorious for requesting huge ascent and descent values. I always disable them using fontsets.
