On Windows, the wrong value was used to calculate the design-to-device scale. The assumption has been that tmHeight in the TEXTMETRIC is the pixel size of the em square, but it is not, it's the height of the font (ascent + descent). The pixel size of the font is defined to be the em square size in pixels. On OS X, the kerning data was never actually read from the font. I've added a lazy initialization for this similar to the one in the FT engine. This was discovered when investigating QTBUG-48546, as it turned out that the kerning information extracted by Qt in this case was different from the one used by Harfbuzz. I've changed testfont.ttf to kern "_2" so that the digit is positioned directly on top of the underscore and constructed a test.
