Japanese cannot be used for title of register_field_group

[Tanabebe]

Hi Team

Regarding the event on the subject, This is probably the case with versions 5.11.2 and later.

For example, if you use register_field_group as below.

if(function_exists("register_field_group"))
{
    register_field_group(array (
        'id' => 'acf_annotation',
        'title' => '注釈',
        'fields' => array (
            array (
                'key' => 'field_99999f0d1406',
                'label' => '注釈',
                'name' => 'header_annotation',
                'type' => 'text',
                'default_value' => '',
                'placeholder' => '',
                'prepend' => '',
                'append' => '',
                'formatting' => 'html',
                'maxlength' => '',
            ),
        ),
        'location' => array (
            array (
                array (
                    'param' => 'post_type',
                    'operator' => '==',
                    'value' => 'post',
                    'order_no' => 0,
                    'group_no' => 0,
                ),
            )        ),
        'options' => array (
            'position' => 'normal',
            'layout' => 'no_box',
            'hide_on_screen' => array (
            ),
        ),
        'menu_order' => 1,
    ));
 }

If the string used for id title in acf_slugify (code part below) of acf-helper-functions.php contains Japanese characters, it becomes an empty string.

$slug = preg_replace( '/[^A-Za-z0-9' . preg_quote( $glue ) . ']/', '', $slug );

In versions 5.11.1 and earlier, you could use Japanese in the title, but did you intentionally allow only half-width alphanumeric characters?

Hey @Tanabebe,

Thanks for the report. We'll look into this! It looks like if you provide a custom key for the field group in register_field_group you'll skip the acf_slugify call which is tripping us up here.

We did change the slugify function, as it is only supposed to support half-width alphanumeric characters - but we'll need to shore up the code in register_field_group to handle that and generate the ID a different way if acf_slugify returns empty.

Hi @lgladdy

Thank you for your quick response.

If the string used for id in acf_slugify (code part below) of acf-helper-functions.php contains Japanese characters, it becomes an empty string.

This was a mistake in the title, not the id, so I will correct it.
