 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,
