By default, the current docker image supports
utf8charset. Unfortunately,utf8in MySQL is not real UTF-8.utf8is only support up to 3-bytes per character. The actual UTF-8 is up to 4-bytes per character (e.g: emoji, astral symbol, wider CJK characters, etc.). To full support UTF-8, we can useutf8mb4charset.Using the current images, I can't force the MySQL to use
utf8mb4because there is a config to force usingutf8which is not compatible withutf8mb4(it made my apps broken ☹).utf8mb4is backward compatible withutf8.
