mysql - Why are information_schema and performance_schema not utf8mb4 (and should I care)? -


i have been going through mariadb installation fine-toothed comb trying update utf8 (3-byte flavor) utf8mb4. it's correct in my.cnf, databases, , applicable tables , columns thereof. , when create new databases no options, create them correct collation. see screenshot of adminer - 2 of 3 infrastructure databases still utf8. is okay? if not, how should change them? server isn't live yet, it's close ready, i'd rather not stupid , break db engine.

enter image description here

do not change in mysql, performance_schema, or information_schema.

beware of indexed varchar(255) character set utf8 -- have trouble limit of 767 bytes on index.
