⿰女硏

Maybe we chould use two IDSes for this case, ⿰女硏 and ⿰妬幵?

According to the pronunciation (Reading: yán), the right component should be 研, why dose the owner of this name or TCA insist to use an irregular form for encoding.

I guess Tao Yang means TD-4A47 ⿰女研 on Comment #15089.



Maybe the reason for TCA to choose TD-7A64 not TD-4A47 is that the person who uses TD-7A64 is a living person based on the evidence.

TCA selected TD-7A64 due to its higher usage frequency among users.
