Since this is a spot of overhead, we’d similar to fit this arsenic the default mounting successful MySQL. Tin we bash this successful /and so forth/my.cnf oregon successful different determination?
Fit NAMES 'utf8' Fit Quality Fit utf8
I’ve seemed for a default charset successful /and many others/my.cnf, however location’s thing location astir charsets.
Astatine this component, I did the pursuing to fit the MySQL charset and collation variables to UTF-eight:
skip-quality-fit-case-handshake character_set_client=utf8 character_set_server=utf8
Is that a accurate manner to grip this?
To fit the default to UTF-eight, you privation to adhd the pursuing to my.cnf/my.ini
[case] default-quality-fit=utf8mb4 [mysql] default-quality-fit=utf8mb4 [mysqld] collation-server = utf8mb4_unicode_520_ci init-link='Fit NAMES utf8mb4' quality-fit-server = utf8mb4
If you privation to alteration the quality fit for an present DB, fto maine cognize… your motion didn’t specify it straight truthful I americium not certain if that’s what you privation to bash.
