1. convert array values to html entities
2. encode json
3. decode html entities 


function utf8_json_encode($json_array){
 
$json_array=array_map('htmlentities',$json_array);
 
return html_entity_decode(json_encode($json_array)); 
}




$myarray= array('nome'=>'Paição','cidade'=>'São Paulo',"À","È","Æ","Ð","Ñ","Ò","Ö",
"Ú","æ","å","ç","ì","ð","ö","ù","ü","§");
echo utf8_json_encode($myarray);

Result is 

{"nome":"Paição","cidade":"São Paulo","0":"À","1":"È","2":"Æ","3":"Ð","4":"Ñ","5":"Ò","6":"Ö","7":"Ú","8":"æ","9":"å","10":"ç","11":"ì","12":"ð","13":"ö","14":"ù","15":"ü","16":"§"}

encode with utf8_encode to avoid null value in json_encode function
<?php
$array= array_map(utf8_encode, $myarray);
json_encode($array)
?>
