Issue of HK and TW characters with 辱 as its composing part

[tamcy]

Source Han Sans isn't very consistent on whether the TW/HK form of 辱 is "stacked (⿱辰寸)" or "contained (⿸辰寸)" (or whether the ㇓ stroke extends to the bottom of the character box). 12 codepoints are involved in this discussion, and here is a screenshot of how they currently look like in Source Han Sans 2.001:

As you see, the chosen form is somewhat inconsistent, summarized as below:

Form	Glyph name
⿸辰寸	uni55D5-TW, uni5AB7-TW, uni6EBD-TW, uni84D0-TW, uni8925-TW, uni910F-TW, uni9392-TW, u270AD-HK
⿱辰寸	uni7E1F-TW, uni8028-HK, uni8028-TW, uni84D0-HK, uni8585-TW, uni8585-HK, uni8925-HK, uni8FB1-TW, uni910F-HK, uni9392-HK

From the above image, HK and TW clearly adopts the stacked form.

The reason that it is inconsistently designed in Source Han Sans is probably due to Taiwan's 國字標準字體母稿. In the published materials, words of such form are not consistently rendered, unlike their corresponding font resources:

You can see that the glyphs shaded in red are adopting the "contained" form, while others are in the "stacked" form. Whether the sans-serif "辱" (shaded in amber) is in a stacked or contained structure is debatable.

Given that

1. The reference glyphs in 國字標準字體母稿 are very inconsistent,
2. The glyphs in the Sung/Kai font resources are very consistent where the stacked form is adopted,

My suggestion is modify existing glyphs and use the form ⿱辰寸 all over the place. Thus my proposed actions:

A) The following 4 characters would need to be adjusted:

Codepoint	Remarks
U+55D5 嗕
U+5AB7 媷
U+6EBD 溽
U+270AD 𧂭	Also need to modify the last stroke of 辰.

B) For the following 2 characters, different CIDs are assigned for TW and HK, but they are essentially the same and can be shared. Suggest to use the TW glyph.

Codepoint
U+8028 耨
U+8585 薅

C) For the following 4 characters, different CIDs are assigned for TW and HK, with different designs. Suggest to use the HK glyph.

Codepoint	Remarks
U+84D0 蓐	Also suggest to update the glyph so that ⿱辰寸 structure is more consistent with the other codepoints. Also the 丿 looks a bit strange, as the stroke in the ExtraLight master should curve a bit more.
U+8925 褥
U+910F 鄏
U+9392 鎒

D) No action needed

The remaining 2 characters are fine, they are listed here just for completeness:

Codepoint
U+7E1F 縟
U+8FB1 辱

Thanks!
