Dear Eiso, Ken, and Suzuki-san,<br>
<br>
FYI, I found a writeup by Eric-san at <a href="https://www.thetype.com/2017/08/11606/">
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.thetype.com%2F2017%2F08%2F11606%2F&data=05%7C02%7Crenzhi.li%40microsoft.com%7C2d47eda370b94c7a907c08dc39453ba1%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C638448217941389266%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=FL7qd5lH8gFctwfhKDLCJNvkVJdu4PJMFK%2Bhh8nK48Y%3D&reserved=0</a>
yesterday and it was a good introductory reading for me. Although I know I am not in the position to say something on this matter, I thought the fact that the ‘hypy’ proposal clearly discourages encoding Pinyin Forms as default would help most of the font
developers (like us) not to get into the controversy in the first place ;)<br>
<br>
Eiso, thank you for the info and I’ll get a copy of 现代汉语词典 just for future reference!<br>
<br>
> highly-specialized fonts, such as those used for preparing official educational materials that may include a mixture of foreign words and Chinese words expressed in Pīnyīn, would benefit from it<br>
<br>
Thank you for your insight as always Ken-san! I personally agree with your views, and I feel the recommendation that the proposal makes allows us to implement Pinyin Forms only for a selection of Chinese fonts, which are specialized for such educational purposes.
That was the reason why I thought Eiso's proposal would be an improvement over the status quo. Apart from the spec, the substitutions could be implemented not only in the proposed ‘hypy’ but also in ‘ssXX’ as a compatibility stopgap, like we often do in Latin
fonts for single-story a/g alternates.<br>
<br>
BTW, another set of documents I had a look for curiosity were ISO 7098 and GB/T 16159 – the former seemed typeset with Cambria, while the latter looked similar to 现代汉语词典’s convention, but they just might not be the sources as official as 汉语拼音方案 or 现代汉语词典, which
Eiso recommends.<br>
<br>
Regards,<br>
<br>

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!<br>
