The variant of 那.

[The following comment is raised by Mr. Ma Shijie.]

It is the top component of U+2D309 𭌉.



It is better to modify the KC-06105 glyph U+2D309 𭌉 to ⿱那𠵨.

⿰尹阝 appears repeatedly in Korean works, clearly as a variant of 那.

Based on Comment #11703. ROK could not modify the K glyph for U+2D309 𭌉. This issue is due to ROK.

On the other hand, ROK could do the horizontal extension for this character later, but there is no KC- or K6-Source references now.

This comment is from individual expert Ma Shijie：

Add new UCV for ⿰尹阝 and 那.

No unification with 那.
TC-2D55 is used in personal names and is unrelated to literary usage.

There are indeed cases of variant writing in the literature, but they are not common. and there are significant differences in character forms. No unification with 那. It's used in personal names.
