Remap suggestion for Kangxi Radicals in CN based on GB18030-2022

[NightFurySL2001]

Some radicals in Kangxi Radicals block of CN region may need to be remapped to match GB18030-2022.

Immediate attention

U+2FC1 ⿁ requires immediate update to change from current CN glyph to TW glyph with broken bottom left stroke. This crashes with U+2EE4 ⻤ which should have connected bottom left stroke. These two radical characters should be differentiated.

Ref: U+2FBB ⾻ and U+2EE3 ⻣ with different direction in Unicode code charts and GB18030-2022. (notice the broken bottom left stroke of U+2FC1 ⿁ although it's minor)

Other remapping suggestions

The following glyphs can be remapped according to GB18030-2022.

1. U+2FCB ⿋ from uni9EF9-CN to uni9EF9-TW
2. U+2F3E ⼾ from uni6237-CN to uni6236-CN
3. U+2FC7 ⿇ from uni9EBB-CN to uni9EBB-TW
4. U+2FCD ⿍ from uni9F0E-CN to uni9F0E-JP
   
   

However, note that such remapping might cause other issues such as #438 .

U+2F4F ⽏ do not have the corresponding glyphs to be remapped. This may or may not be added.

Additional: U+2EC1 ⻁ radical supplement should probably mirror CN of U+864E 虎 and map to uni864EuE0101-JP instead, such that uni864E-CN can be freed up. Serif is mapped to uni864EuE0101-JP.
