 I spent hours before discouvering why wp_insert_term doesn't want to
 create some of my categories list;

 {{{
 $alphabet = array (
         array( 's', 'sth' ),
         array( 'ṣ', 'sth' ),
         array( 'h', 'sth' ),
         array( 'ḥ', 'sth' ),
         array( 'd', 'sth' ),
         array( 'ḍ', 'sth' )
 );

 foreach ($categories as $category )
 {
         if( term_exists(  mb_strtolower($category[0]), 'category' ))
                 continue;
         else
                 wp_insert_term( $category[0], 'category',  array( 'slug'
 => $category[0] ) );
 }
 }}}

 term_exists() doesn't make a difference between "normal characters" and
 diacritic characters.
