#9327 shows that we are already living with script-hybrid characters without any problem. Since the nature and attributes of these characters are not fundamentally different from CJK Ideographs, I see no need to postpone.

Firstly, having already encoded similar characters does not necessarily mean that the same action can still be performed in the future.
Secondly, the encoded characters belong to the extended set E And F, The people involved in the coding work at that time may not have realized that these were script-hybrid characters.
Thirdly, the experts who raised the question had not yet participated in international encoding work at that time.
Fourthly, from the glyph of character form, the encoded characters cannot be distinguished from normal Hanzi through the proposed form, and it cannot be seen that their components are kana. The components fully conform to the writing and form of Hanzi components.
Fifthly and most importantly, after encoding such characters, their attribute annotation and component splitting methods will have an systematic impact on IRG PnP and Unihan database. The application of data carries too much risk.
I still recommend not placing such characters in CJK sets.

The UTC agrees to withdraw this character per #11545.
