Add another Currency

OK I found solution on WordPress_org “https://wordpress.org/support/topic/currency-22”
This code should be placed in a child theme functions.php.

// Add currency 'Ukrainian Hryvnia' with code '& # 8372;'
function rec_extra_edd_currencies( $currencies ) {
	$currencies['₴'] = __('Ukrainian hryvnia', 'my_domain');

	return $currencies;
}
add_filter('epl_get_currencies', 'rec_extra_edd_currencies');

Thx!
