Recently I have an issue with HarBuzz doing strange values for Microsoft mincho for the descender in vhea.</div><div><br></div><div>Looking at ISO/IEC 14496-22:2015, section 5.7.7, in version 1.1 version of the table's "vertTypoDescender" description, it says "... For example, a font with an em of 1000 fUnits will set this field to 500".</div><div><br></div><div>Then in the next page, the example is "Minus half the em-square height".</div><div><br></div><div>I think in the first description a few "minus" and "-" should be added. Thus the anomaly with Microsoft mincho (its descender field in vhea has a +ve value...)</div><div><br></div><div>Hin-Tak</div></body></html>
