The 尤, 冘 and 无 components may need unification

[Marcus98T]

I suggest that we should unify the 尤 and 冘 components (with my preferred JP form where 丿 and 乚 touches) for all regions whenever possible, saving a bit of glyph space. There's nothing that says the 丿 and 乚 should not touch for CN/TW/HK locales. This similar issue which I reported earlier for Serif is separate for Source Han Sans to avoid confusion.

Here are the characters to review:

莸就僦噈憱殧蹴鹫鷲蹵

The v1 reference is from a Source Han Sans fork called GenYoGothic (源樣黑體 TW version) as I cannot install v1 and v2 at the same time. Glyphs are largely the same as v1 Sans, especially those which are removed v1 JP glyphs.

LEGEND
Green - the v1 glyph can be restored to replace all locales.
Blue - if possible, the v1 glyph may be restored to replace only the JP/KR/CN locales.
Red - the glyphs to be replaced by the v1 JP glyphs.
Orange - the glyphs to be adjusted, even those within the JP/KR locales, if ever so slightly.
Magenta/Pink - Replace with v2 JP/KR forms and remove existing glyph.
Light green - replace with HK form and adjust glyph.
White - no change needed.

For 尤, I did put the character through my font list and it appears that maybe it should be treated separately for the CN region, but how the 丿 and 乚 strokes are applied is still inconsistent, especially between Sans and Serif. I probably suggest we review first and whether conforming all these characters containing 尤 to JP forms is acceptable for the CN region, and please comment with concrete evidence to prove otherwise.

In addition to this, the 无 component should also be merged to the JP forms. Restore v1 JP glyphs if needed to replace the corresponding CN glyphs, otherwise for any essential regional difference, adjust the glyphs.

Also applies to Serif. I am unfortunately too busy to list down what adjustments are exactly needed.
