Apparent variant of : 𩦧 (U+299A7). This is not an exact match. We would need a new UCV to equate 曼 with ⿳日罒方and 㬅.

TCA has no objection to the merger of UCV#278 and 465, but hopes to encode WS2024-04254: Regarding the right-hand part of the character form, 曼 is the standard character, while 㬅, 𭦗, and ⿳日罒万 are all vulgar forms of 曼. However, in this set of relationships, ⿰馬曼 is to be unified with ⿰馬㬅, which means the standard form is being unified with a variant form. Logically, the standard form should take precedence over variant forms.

The simplified form is in Extension I.

Agree with comment #5493. For ideographs used in registered residence system of government, it's better to unify them not just based on the rationale from a very professional view. We should handle characters used in registered residence systems in a more practical way. I recommond member bodies agree with this point to submit a proposal together and add following principles in IRG PnP( a rough draft).
For ideographs used in Government Administration System, if
1. There are structual differences which can cause the change of radical;
2. The different structures are non-cognate with each other in modern times and have major stroke differences(in this case, it is 方 and 又);
The two unifiable ideograph can be disunified under the request of Regional or national member bodies.

No government can make all window staff understand the source of Chinese characters and the corresponding relationships between various shapes like IRG experts. However, the window staff are one of the main groups who will use the characters after the characters are encoded.

As the simplified variant U+2EE4E 𮹎 (⿰马曼) already exists, it is useful to encode TE-4340. If TE-4340 is unified to 𩦧 (U+299A7) then U+2EE4E will remain an orphan simplified form as it cannot traditionalfy to U+299A7.

Agree comment #5691 as simplified form already encoded then it makes sense to encode the traditional form.

Thank you all. Need to be added back to the M set.
