Description

I would like to raise the 辶 component from this discussion again. I think that the CN and JP glyphs for 辶 component should be unified in Source Han Sans (and to Source Han Serif).

I do know that this was rejected by Ken Lunde after consultation with the designer team (probably from Changzhou Sinotype at the time) but there is now a new team from Arphic Technology working with Adobe and thus I would suggest consulting this decision with both Changzhou Sinotype and Arphic Technology.

The points are as follow:

There are no official documentation or mentions of 辶 to be designed as a single stroke in any of the official documents from Tōngyòng Guīfàn Hànzìbiǎo, or any of its predecessors. Similar decisions with official documentation in say, Standard Form of National Characters, which mentioned that the two strokes in 立 and 豆 should be touching both top and bottom line, are not even implemented in Source Han Sans.
辶 is designed similar to JP in some SC fonts, such as Microsoft YaHei (Windows default system font). The current design of 辶 is mainly a relic from the Shanghai Song style.
Sharing of 辶 glyph between CN and JP can reduce a significant amount of CIDs to be used for expanding the character set.

This suggestion should be considered by both Changzhou Sinotype and Arphic Technology as they may have better knowledge on this issue.

P/S: If this is to be viewed as a regional difference, then the requirement of two dots in 立 and 豆 to be connected to the top and bottom stroke should be implemented for TW and HK as this is a written requirement in Taiwan's 國字標準字體教師手冊, unlike this differentiation of 辶 component which is not specified anywhere in any of China's official document.
