https://github.com/adobe-fonts/source-han-sans/issues/34 I've now looked up the discussion in the bug tracker, and I would like to know why you think that there is a bug. While the behaviour is indeed different, I like centered glyphs more... > [...] Attached image file is the result of comparison. As shown in > the image, only freetype puts glyphs center-aligned.

The basic question is whether the font contains information on the vertical baseline – this is something I haven't seen mentioned anywhere. However, in case it is up to the rendering engine to select the default position of glyphs in vertical typesetting, I second Behdad that changing FreeType just for the sake of optical compatibility is not helpful.
