[MPEG-OTSPEC] Two GSUB Proposals for OFF: 'cabp' and 'hypy'

[Takaaki Fuji 藤 貴亮]

Dear Eiso,

I'm just curious, but for ‘hypy’, is there any good source I can look at for the ‘official' glyph forms of Hanyu Pinyin?

If I understand the issue correctly, ‘hypy’ is not only about the Futura-like one-story a/g shown in Example, but also the tone marks are preferred to have a 'reverse-modulation’; while an acute is always stroked from top to bottom as a Latin accent, as a Pinyin mark it goes upwards from left to right to illustrate the second/rising tone. I imagine this conflict/divergence has long been such an issue in a dual-script situation, so switching between the two via GSUB sounds like a great improvement to me!

Thank you,

Takaaki Fuji
