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

[Hin-Tak Leung]

 For those who want to read the source material, it seems that the canonical sources for GBZ 40637 might behttps://www.chinesestandard.net/AMP/English.amp.aspx/GBZ40637-2021

https://openstd.samr.gov.cn/bzgk/gb/newGbInfo?hcno=52E2DE28D439C1937EE09AE4B5AA615B

For the English and Chinese version of it respectively (behind pay walls), and a somewhat reliable Chinese version available for download at:
https://archive.org/details/GB-Z40637-2021/page/n5/mode/1up

I am mostly with Ken Lunde on this: transliteration itself is a work-around (trying to approximate one language's sound with another), and diacritics on transliteration is a refinement of a workaround... for actual scholarly work, the traditional way of indicating the pronunciation of a rare word in Chinese is to say "XY 切" where you indicates the starting consonant and the ending vowel with two common native words.e.g. my surname "梁"'s Cantonese pronunciation might be written down as "連揚切", where you take the consonant of the first (連"leen") and join with the ending vowel of another ("揚""yeung") to form "leung". Most people can't quite pronounce English "leung" correctly anyway, so the traditional way of annotating it as e.g. "連揚切" would be preferable... it is somewhat a lost cause to try to standardise on hyphenation and diacritics of transliterations...

 Dear Eiso, Fuji-san,

I checked 現代漢語拼音方案2012 available at

http://edu.shandong.gov.cn/attach/0/b72295c44ff442c8b333a481f524dbe9.pdf

I guess, the glyphs you want to care might be:

"a" in "ai" (哀), "uan" (弯), "Van" (冤) in 韻母表
"g" in "ang" (昂), "eng" (亨的韵母), "ieng" (英), "ueng" (翁), "veng" (雍) in 韻母表

Am I understanding correctly?

漢語拼音方案1958 (I'm unsure the source of this scanned image):

http://www.moe.gov.cn/ewebeditor/uploadfile/2015/03/02/20150302165814246.pdf

there is no clear distinction of the typeface for "a" & "g".

A distinction of "a" is mentioned in the 四、声調符号, special "a" is used for 軽声,
maybe it would be the update introduced in 2012.

But yet I'm unsure about the background to distinguish "g".

Regards,
mpsuzuki

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!
