unify to 工?

The Japanese reading of this character is コウ, which is the same as 工.

If the IRG unifies, UCV #408 needs to be updated.

The person who submitted this ideograph to the UTC pointed out that U+2B7B9 in the Extension D block is a disunification example. My own checking found that U+2D5FB in the Extension F block, which appears to be cognate with 巠 (U+5DE0) according to the Moji Jōhō Kiban database, is another example.

The same as Z2-6 mentioned in IRG N2733R, but it is the real Hanzi/Kanji. It is better to remove it from the CJK component. It will be a helpful one for IDS. We can add it to UCV with 工 as the components but encode this one separately.

Please provide more evidences to prove the rationality of the glyph. We have emphasized the importance of multiple pieces of evidence in encoding work for multiple times.

This is the 29th ideograph in document L2/23-130, and I requested that the document author provide more evidence.

Related to the above: 旧表題部 (Former title section. It seems that this was the title section until about 1960.)



旧土地台帳 (Land registration record, which was used from the Meiji era to 1960s. In the second one, "工" and "空" have been corrected to write characters similar to "ユ." It seems the name of this place was also written as "万空内.")
