Node, Sequelize, Mysql - How to define collation and charset to models?

In the part where u define sequelize

var sequelize = new Sequelize('database', 'username', 'password', {
  define: {
    charset: 'utf8',
    collate: 'utf8_general_ci', 
    timestamps: true
  },
  logging:false
});

For Table level Changing

sequelize.define('songs', {
  name: DataTypes.STRING,
  link: DataTypes.STRING,
  artist: DataTypes.STRING,
  lyrics: DataTypes.TEXT,
  writer: DataTypes.STRING,
  composer: DataTypes.STRING
}, {
  charset: 'utf8',
  collate: 'utf8_unicode_ci'
});
