ERROR 1115 (42000): Unknown character set: 'utf8mb4'

Question

I have a MySQL dump, which I tried to restore with:

mysql -u\"username\" -p\"password\" --host=\"127.0.0.1\" mysql_db < mysql_db

However

Answer 1

maybe whole database + tables + fields should have the same charset??!

i.e.

CREATE TABLE `politicas` (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `Nombre` varchar(250) CHARACTER SET utf8 NOT NULL,
  -------------------------------------^here!!!!!!!!!!!
  PRIMARY KEY (`ID`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
  -------------------------------------------------^here!!!!!!!!!
