The evidence presented conflicts with the version of GB/T 12052-1989 provided by China (Mr Zhang Zhoucai) for the preparation of the original version of the URO, attached below. This version clearly shows ⿵門西. Moreover, this block of the standard is arranged in Hangul alphabetic order and the character in question, read 서, is situated between 虄 read 산 and 縇 read 선. The reading 서 clearly reflects the Korean reading of 西. We need to resolve the discrepancy between the 2 documents. My understanding is that this block of GB/T 12052-1989 is supports Korean language bibliographic data used in the National Library of China. We should be able to confirm the shape based on that data. Or, perhaps Korea can provide independent evidence supporting that shape. The current evidence alone is not acceptable.

1. GK-6841 (or G1-7D47) and GK-6863 (or G1-7D69) were removed from U+58ED 壭 from U+5655 噕 respectively because they don't match the ones in GB 12052.

https://unicode.org/wg2/docs/n4104.pdf (see Resolution M58.03)
This means that the form in the original GB 12052 is regarded as the final authority.

2. Actually, the virtual row 93 of GB 12345 is not always correct either. 0x7D3A is missing 罒, but 72-20 (0x6834) the original GB 12052 is not. And GK-6834 (or G1-7D3A) is mapped to U+56D5 囕, with 罒.

Citing http://std.dkuug.dk/JTC1/sc2/wg2/docs/n4008.pdf is circular reasoning by referring to a possibly bad decision based on the same faulty evidence and cannot be accepted. We still need independent confirmation of the existence and form of this character.

For this particular ideograph, I agree with Lee's explanation. Furthermore, the component ⿱一曲 does not appear in *any* other ideograph, which makes its form highly suspicious. I would also like to point out that treating a standard that hasn't been touched in over 30 years as a final authority, particularly when its representative glyphs were drawn by hand, is not sound. Instead, sound analysis is necessary to make a final determination, which has been demonstrated. The UTC shall withdrawn this ideograph and record it as an error form of U+95AA 閪.

Withdraw.
