http - PHP CURL isn't processing encoded return data properly

Question

Im have some minor encoding issues. Im getting a json data string from here (try it yourself):

http://cdn.content.easports.com/fifa/fltOnlineAssets/C74DDF38-0B11-49b0-B199-2E2A11D1CC13/2014/fut/items/web/179899.json

The name in the data is shown like this

Ari Sk?olason

How can I fetch this data with proper encoding so its Ari Skúlason?

I tried switching it to utf-8 like this in php

echo mb_convert_encoding($r,'ISO-8859-1','utf-8');

which got me closer, but its still not right

Ari Sk?lason

my php curl request:

$location = 'http://cdn.content.easports.com/fifa/fltOnlineAssets/C74DDF38-0B11-49b0-  B199-2E2A11D1CC13/2014/fut/items/web/179899.json';
$ch = curl_init($location);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                                                                                                        
'Accept: application/json'));
$r = curl_exec($ch);
curl_close($ch);
echo mb_detect_encoding($r);
$r = mb_convert_encoding($r,'ISO-8859-1','utf-8');

print_r($r);

Answer 1

set another curl option for CURLOPT_ENCODING and set it to "" to ensure it will not return any garbage

   curl_setopt($ch, CURLOPT_ENCODING ,"");
