Description:
--character-set-client-handshake is supported for transition from 4.0 to 4.1.

https://dev.mysql.com/doc/refman/5.6/en/faqs-cjk.html#faq-cjk-how-use-4-0-charset

Almost of all MySQL 3.23/4.0 are gone, so it's time to deprecate/remove this feature.

I think all user using --character-set-client-handshake keeps old my.cnf without that meaning, so When migration from old MySQL to New MySQL, a user should specify charset on their client instead of keeping --character-set-client-handshake in his my.cnf.

How to repeat:
N/A

Suggested fix:
Deprecate character-set-client-handshake in MySQL 8.0.x, and Remove in the future release.

Hello Meiji-San,

Thank you for the report and feedback.

regards,
Umesh
