[luatex] Luaotfload still cannot embed several new CJK fonts in Mac OS X 10.11 El Capitan

[Hironobu Yamashita]

Hi all,

I think Kazuki says:

It is true that **most of** the collection fonts available in the world have a subfont
whose postscript name is exactly same as its fontname, however, it is NOT true
that **all of** the collection fonts do.

And he is right: some of the examples are Apple's new CJK fonts and what Yusuke
has sent to us. And the patch Kazuki has sent works fine, I think.
