I'm in great trouble, it seems that the CODE output by the MB Builder is multibyte encoded.
The next "name".
'fields' => [
'id' => $prefix . 'home_main_title',
'type' => 'textarea',
'name' => "###\xe3\x82\xbf\xe3\x82\xa4\xe3\x83\x88\xe3\x83\xab###",
I want to customize the custom field created by MB Builder with functions,
but I can't read the multibyte text and it's very difficult to use.
Is there a way around this?
