I am using SEOStats library's getSerps method to query google.ch for particular keyword. When I do that result is having "?". I believe they are from swiss language's special characters.
I want to display them correctly on web page. I have already tried utf8_encode and utf8_decode functions with no luck.
If you want to generate this issue on your side then just make following change on SEOstats\Config\DefaultSettings.php file.
const GOOGLE_TLD = 'ch';
And call example/get-google-serps.php file with keyword "web hosting". You will see many '?' in resulting php array.
Thanks for help in advance.

I've installed SEOStats via composer composer require seostats/seostats. If you download library from github it may differ.
Here is line from my \vendor\seostats\seostats\SEOstats\Services\Google.php:
$curledSerp = utf8_decode( self::gCurl($nextSerp, $ref) );
Here is utf8_decode function (http://php.net/manual/en/function.utf8-decode.php). This function converts all utf8 chars to iso. All chars that cannot be converted by this function are replaced with ? Try to remove utf8_decode function and you'll have all your utf-8 chars safe.
