Hi, I would like to know how to sort a repeater field when some of the words can have accents (french names).

Here is my code

function my_acf_load_value( $value, $post_id, $field ) {
	
	// vars
	$order = array();
	
	// bail early if no value
	if( empty($value) ) {
		return $value;
	}
	
	// populate order
	foreach( $value as $i => $row ) {
		$order[ $i ] = $row['field_5ab126349ce3a'];
	}
	
	// multisort
	array_multisort( $order, SORT_DESC, $value );
	
	// return
		
	return $value;
}

add_filter('acf/load_value/key=field_5ab126349ce3a', 'my_acf_load_value', 10, 3);

Here is the result
Mathieu
Roland
Rébecca
Zac
Édouard

Roland should be after Rébecca and Édouard should be first

There isn’t any way to do this. I did a search on ‘php sort words with accented letters in correct order’ and found only the results that say it can’t be done short of building your own comparison functions. PHP sorts base on the numeric value of the character in the character set. https://stackoverflow.com/questions/39035477/php-natsort-with-accented-letters
