In CakePHP3 migrations (or Phinx), how to use utf8mb4 charset?

Question

Creating MySQL table or adding columns with CakePHP3 migrations, charset is set to UTF8. Is there the way to set charset utf8mb4?

(and, i found this issue... https://github.com/robmorgan/phinx/issues/74)

Answer 1

You can set the collation when you call the table() function.

public function change() {
     $table = $this->table('FooBar',['collation'=>'utf8mb4_unicode_ci']);
     //.....
}

You can only set the collation type. The character set will be extracted from that collation string. There for the above will have a character set of "utf8mb4".
