The above page shows several characters related to the top component 䄪, all of them should be unified to 𥝢 as the top component, such as...
U+68C3 棃 vs ⿱䄪木


U+7282 犂 vs ⿱䄪牛


U+9ECE 黎 V1-6D2E vs ⿱䄪𱥯


U+74C8 瓈 vs ⿰王⿱䄪𱥯


U+853E 蔾 vs ⿳艹䄪木



However, there is only U+9ECE 黎 has the V-Source reference and the top component shows 𥝢 not 䄪.
Maybe we need to make something.

Solution 1:
Modify the glyph and IDS for this character to ⿰石棃.
Do the V-Source horizontal extensions for U+68C3 棃, U+7282 犂, U+74C8 瓈, U+853E 蔾 like 黎 in future.

Solution 2:
Change V1-6D2E glyph for U+9ECE 黎 to ⿱䄪𱥯.
Treat ⿱䄪X as Vietnam/VNPF convention.
Do the V-Source horizontal extensions for U+68C3 棃, U+7282 犂, U+74C8 瓈, U+853E 蔾 as ⿱䄪木, ⿱䄪牛, ⿰王⿱䄪𱥯, ⿳艹䄪木 in future.
Change IDS for this character to ⿰石棃, but keep the glyph.

The best solution is 1, modify VN-F03D1 to use 𥝢.

Nom Na Tong and other Nôm fonts, such as Han-Nom Minh and Han-Nom Kai use 𥝢 for most of the characters shown above and some others:

Chars with 𥝢 in Nom Na Tong: 棃犂黎瓈𥗍𨛫㰀嚟𠠍𤂱𤑬



The only exceptions we can find are U+853E and VN-F03D1.

䄪 is not necessarily standard. Other dictionaries show 𥝢 for U+68C3 and U+853E, as in the entries below from Taberd.

Changing the glyphs of U+853E and VN-F03D1 will be the least disruptive and conform to Vietnamese usage. We can do the horizontal extension after we change U+853E.

We will add 𥝢 as a normalization rule for 䄪.

We have an update to this glyph for the change proposed above.
