Description Myles C. Maxfield 2014-09-28 20:36:42 PDT

Technically, 'kern' isn't in the OTF spec. GPOS is instead.

Comment 1 Myles C. Maxfield 2015-04-06 10:34:14 PDT

Windows doesn't read kern tables

Comment 2 Myles C. Maxfield 2016-02-25 13:05:54 PST

This is causing fast/text/svg-font-face-with-kerning.html to fail on Windows with the SVG -> OTF Converter.

Comment 3 Myles C. Maxfield 2016-04-04 15:57:43 PDT

I think the quote that is most relevant is

"OpenType™ fonts containing CFF outlines are not supported by the 'kern' table and must use the 'GPOS' OpenType Layout table." from https://www.microsoft.com/typography/otspec/kern.htm
