Sat 21 Dec 2013 06:27:36 PM UTC, comment #6: Ah, I forgot to mention: those are DejaVu Sans Bold U+039B and U+0394, which show the same problem as U+1D760 and U+1D759. The latter are just intrinsically bold and not in the regular typeface. |

Fri 20 Dec 2013 06:20:44 AM UTC, comment #2: I've just downloaded the latest DejaVu version; the font `DejaVuSans.ttf' (version 2.34) doesn't contain a glyph for U+1D760. Obviously, you are using a different font... |

Excellent, thanks! FreeType now behaves identically to the Windows engine.
You should file a bug report to the DejaVu people so that the bad hinting gets fixed.
