from time to time I register new accounts and can't login to them if I used utf8 or utf8mb4.

utf8mb3 (previously utf8_general) is default on mysql, it used 3 bytes for utf8 format, it been splitted within mariadb 10.4+ versions where utf8mb4 uses 4 bytes and to utf8mb3 which uses previous range (3 bytes)

utf8mb3 based queries, datas are fine with utf8mb4 but utf8mb4 based range is not compatible to utf8mb3 if data takes all 4 byte characters range

i mean, utf8mb3 -> utf8mb4 (OK)
utf8mb4 -> utf8mb3 (potentially compatible if data doesn;t takes whole 4 bytes range)

but yet older applications compiled within mysql version package may could work wrong with these two types, for example, spellwork application.
