18606	wp_insert_term and wp_create_category fail on diacritics names	abdessamad idrissi		"To create a category with the name 
{{{
Ḍ

using either wp_insert_term or wp_create_category, an HTML entity representing the character must be given;
so this won't work : 

{{{
wp_create_category( 'Ḍ' );
wp_insert_term( 'Ḍ' );
}}}

but this will work 

{{{
wp_insert_term( mb_strtolower('Ḍ'), 'category',  array( 'slug' => html_entity_decode('Ḍ', ENT_QUOTES, 'UTF-8') ) );
}}}

What is strange is when the category is created using the admin panel it works with the original diacritics name,
