Yes. Also, the text itself is invisible.

The font is buggy; it contains blank glyphs for a whole bunch of Latin characters that we try to use to show the font name but since the glyphs are blank nothing shows up. Thos should be reported to font authors, they should either drop the blank glyphs allowing fallback to kick in, or provide usable glyphs for them.
