Full-width comma (uniFF0C-TW)'s design reverted to pre-v1.001 version

[tamcy]

The design of TW's full-width comma (uniFF0C-TW) and CN's full-width semi-colon (uniFF1B-CN) were adjusted in version 1.001, quote #36:

• Adjusted the TW glyph for U+FF0C ，, uniFF0C-TW, by making its shape the same as the JP glyph, uniFF0C.
• Adjusted the CN glyph for U+FF1B ；, uniFF1B-CN, by making its comma component the same as that of the JP glyph, uniFF1B.

However, the above changes have been reverted in v2.000.

Also, uniFF0C-TW is supposed to further modified by shifting it slightly downward after v1.001, also quote #36:

Adjust the TW glyph for U+FF0C ，, uniFF0C-TW, by shifting it slightly downward.

This hasn't been done in v2.000. The problem is that the current position doesn't look visually aligned to the center. You may refer to the position of this glyph in Source Han Sans.

For what it’s worth, here is a visual comparison of uniFF0C-TW between v1.001 and v2.001:

v1.001

v2.001

• The v2.001 comma (which was reverted to v1.000) is weirdly “tilted” (not visually upright). Also, there is a non-smooth/pointy bump on the northeast corner of the glyph.
• Both v1.001 and v2.001 commas are visually too high with respect to the ideographic em-box, and both glyphs are smaller than the JP/CN form. Ideally, the TW/HK glyph shape should be identical to the JP/CN shape, and visually centered.
