Because on my system, there's no font for this codepoint (as I'= d expect), and therefore Emacs displays it as "glyphless" character, showin= g a box with the character's code in hex, and that avoids the assertion vio= lation=2E So please step through x_produce_glyphs when Emacs needs to produce a glyp= h for this character, and tell how you end up with both ascent and descent = values zero=2E It isn't supposed to happen with valid fonts=2E
