Design difference between Source Han Sans SC and Source Han Serif SC 2

[KazunariTsuboi]

21 characters were found in Source Han Serif SC that have different design with Source Han Sans SC. They are ⻁ (U+2EC1), ⻪ (U+2EEA), 懲 (U+61F2), 乑 (U+4E51), 堩 (U+5829), ⼬ (U+2F2C), 巆 (U+5DC6), 濹 (U+6FF9), 衋 (U+884B), 贗 (U+8D17), ⿋ (U+2FCB), 㗴 (U+35F4), 䙶 (U+4676), 䜛 (U+471B), 䞅 (U+4785), 䟡 (U+47E1), 𩻄 (U+29EC4), 㧤 (U+39E4), 㵮 (U+3D6E), 䎉 (U+4389), 䕎 (U+454E)

Thank you. A small number of these issues have been fixed for the forthcoming dot release, and some of them are Source Han Sans issues, not Source Han Serif ones. Also, some of them are intentional typeface design differences.

I will go through this list in the next few days to determine their dispositions.

Here's my analysis of the 21 glyph pairs that you identified:

Characters	Serif	Sans
⻁ U+2EC1	Fixed for Version 1.001	OK
⻪ U+2EEA	Fixed for Version 1.001	OK
懲 U+61F2	OK	Known issue (fix CN glyph)
乑 U+4E51	OK	Remove CN glyph; Use JP glyph for CN/TW
堩 U+5829	OK	Known issue (fix CN glyph). See U+21377 𡍷
⼬ U+2F2C	Fixed for Version 1.001	OK
巆 U+5DC6	Add CN glyph	OK
濹 U+6FF9	OK	Known issue (change mapping to JP variant)
衋 U+884B	OK	Known issue (for both JP and CN glyphs)
贗 U+8D17	Rename TW glyph to be CN glyph	OK
⿋ U+2FCB	OK	CN glyph for U+9EF9 needs to be adjusted
㗴 U+35F4	OK	Known issue (add CN glyph)
䙶 U+4676	Fix CN glyph	OK
䜛 U+471B	Fix CN glyph	OK
䞅 U+4785	Fix CN glyph	OK
䟡 U+47E1	OK	Fix CN glyph
𩻄 U+29EC4	OK (typeface design difference)	OK (typeface design difference)
㧤 U+39E4	OK (typeface design difference)	OK (typeface design difference)
㵮 U+3D6E	OK	Remove CN glyph (it also has a subtle interpolation issue)
䎉 U+4389	OK	Fix CN glyph
䕎 U+454E	OK	Known issue (fix CN glyph)

In other words, you found five Source Han Serif issues (one new CN glyph needs to be added, three CN glyphs need to be fixed, and one TW glyph needs to be changed to a CN glyph) and five Source Han Sans ones (two CN glyphs need to be removed, and three CN glyphs need to be fixed). The rest are either addressed in the forthcoming Source Han Serif update, or are already known Source Han Sans issues.

I will update the appropriate issues within the next day or two to consolidate the above, and then will close this issue.

(Thank you, @miguelsousa, for turning my data above into a easy-to-read table.)

The above changes are now either reflected in the appropriate issues (Source Han Serif) or in my own notes (Source Han Sans Version 2.000), and therefore consolidated.
