Consider either unifying the width of both sides or bending the vertical stroke.

Is this character a variant of 𫵮?

All evidences support variant of 𫵮. So unify to 𫵮 (U+2BD6E).

Also, in SAT, 一切經音義: 從又持～啇, ～音瑟臻反, 古文作曹.
So according to SAT, it is used as 甡, so unify to 甡 (U+7521).

［唐］慧琳 撰 ：《一切經音義》卷第六十二，《中華大藏經（漢文部分）》，中華書局，1993年02月，第1版，第704頁。

（⿰丰丰）作为“𠁳”“𣍈”“𧯮”“𧯽”“𫪙”“彗”等字的传世楷书部件，古今学者普遍认可其由两个“丰”字并列构成，但对于其中“丰”形字的来源与含义，存在不同见解：有源自“𡴀（丰）、𤯓（生）、丯（介）、玉”等不同论述；其功能或表音，或表义，诸家观点不一。正因其讨论纷繁，（⿰丰丰）与𫵮 (U+2BD6E)、甡 (U+7521)在古籍中屡见并现。

The glyph (⿰丰丰) appears as a component in the transmitted regular script forms of characters such as "𠁳", "𣍈", "𧯮", "𧯽", "𫪙", and "彗". While scholars generally agree that it consists of two "丰" elements arranged side by side, there are divergent views regarding the origin and meaning of this "丰"-shaped component. Some interpret it as derived from "𡴀 (丰)", "𤯓 (生)", "丯 (jie)", or "玉 (jade)". Its function is variously understood as phonetic or semantic, and no scholarly consensus has been reached. Due to the extensive discussions surrounding this component, (⿰丰丰) frequently co-occurs with 𫵮 (U+2BD6E) and 甡 (U+7521) in ancient texts.

基于以上情况，提出以下建议：

Based on the above, the following suggestions are proposed:

（一）关于编码处理 #10773
鉴于（⿰丰丰）与𫵮、甡在字形、字义及实际使用中存在复杂关联，但并非全同关系，直接将其认同为𫵮或甡既不符合学术讨论现状，亦不利于古籍数字化的精确处理。建议对（⿰丰丰）予以单独编码。

(1) Regarding Encoding #10773
Given the complex relationships among (⿰丰丰), 𫵮, and 甡 in terms of glyph form, meaning, and actual usage, they are not identical. Directly unifying (⿰丰丰) with either 𫵮 or 甡 would not reflect the current state of scholarly discussion and would hinder precise processing in the digitization of ancient texts. It is recommended that (⿰丰丰) be encoded as a separate character.

（二）关于异体关系界定 #10634
（⿰丰丰）与𫵮 (U+2BD6E)、甡 (U+7521)存在广义上的异体字关系，尤以与𫵮的关系更为密切。在其独立出现时，多用作“𫵮”之异体（如evidence 5所示），可作为参考。

(2) Regarding Variant Relationship #10634
(⿰丰丰) has a broad variant relationship with 𫵮 (U+2BD6E) and 甡 (U+7521), with a particularly close relationship to 𫵮. When it appears independently, it is often used as a variant of 𫵮 (as shown in evidence 5), which may serve as a reference.

（三）关于字形设计建议 #4005
建议参考以（⿰丰丰）为构件的“𠁳”“𣍈”“𧯮”“𧯽”“𫪙”“彗”等字的楷书形态。为保持部件形态统一、符合字理逻辑，（⿰丰丰）宜采用左右等宽结构，竖笔不弯曲。

(3) Suggestions for Glyph Design #4005
It is recommended to refer to the regular script forms of characters that use (⿰丰丰) as a component, such as "𠁳", "𣍈", "𧯮", "𧯽", "𫪙", and "彗". To maintain component consistency and adhere to the logical structure of the character, (⿰丰丰) should be designed with equal width on both sides, and the vertical strokes should not be curved.

（四）关于SAT数据及evidence 9的说明 #10773
SAT数据库引《一切经音义》文句“從又持~商，~音瑟臻反，古文作曹”，可能存在“啇”字衍文之误。已提供《中华大藏经》相应截图作为佐证。evidence 9引用此条文献，虽存在排版或标点瑕疵，但对上述结论无实质影响。

(4) Regarding the SAT Data and Evidence 9 #10773
The SAT database cites the 一切經音義: "從又持~商，~音瑟臻反，古文作曹." This may contain an erroneous insertion of the character "啇". A corresponding screenshot from the *中華大藏經* has been provided as supporting evidence. Although Evidence 9 references this passage and may contain typographical or punctuation errors, this does not substantially affect the conclusions above.
