Restore v1 JP glyph for 狅 (U+72C5) to replace the HK glyph if possible

[Marcus98T]

A long time ago, someone apparently missed the fact that there was a JP glyph for 狅 (U+72C5) that actually suited HK in #215 (which is already long closed). As we knew, the JP glyph was already removed in v2, but unfortunately, Adobe ended up reinventing the wheel and had Arphic create a similar looking glyph for HK, which in fact looks slightly different from the v1 JP glyph.

Blue: v1 JP
Red: v2 HK

I know it's a waste of effort, and it's a bit late to ask for this, but I highly recommend to restore the v1 JP glyph for 狅 as it looks better than the HK glyph, and remove the latter. The restored v1 JP glyph can be used for HK, KR and CN as well (for which the latter two locales, as well as the JP locale, are currently using the TW glyph, which is already known to be incorrect).
