Question

I'm having a bit of an issue, im trying to pull basic metadata from an external URL, I have successfuly got it to do so for the most part but its causing a few character issues on letters that are Ä ä ö are coming out like mäenjaksa7-300x200.jpg when i call the images url which is actually mäenjaksa7-300x200.jpg, my code is below and thank you for helping.
function file_get_contents_curl($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($ch);
curl_close($ch);
return $data; }
$html = file_get_contents_curl($params['url']);
//parsing begins here:
$doc = new DOMDocument();
#$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('title');
//get and display what you need:
$urltitle = $nodes->item(0)->nodeValue;
$metas = $doc->getElementsByTagName('meta');
for ($i = 0; $i < $metas->length; $i++)
{
$meta = $metas->item($i);
if($meta->getAttribute('name') == 'description')
$description = $meta->getAttribute('content');
if($meta->getAttribute('name') == 'keywords')
$keywords = $meta->getAttribute('content');
if($meta->getAttribute('property') == 'og:image')
$ogimage = $meta->getAttribute('content');
if($meta->getAttribute('rel') == 'image_src')
$relimage = $meta->getAttribute('content');
}
if( empty($ogimage) ) {
$metaimage = $relimage;
} else {
$metaimage = $ogimage;
}

Perhaps you have to make sure that your url header have content-type -> charset to utf-8 or appropriate one. You have to make sure that your url is not content none Ascii character or make sure you have properly set the appropriate "character’s encoder". Maybe i haven’t well understood your problem, however look at this example which have not relation to your code but can be useful:
$url = "http://www.example.com/services/calculation";
$page = "/services/calculation";
$headers = array(
"POST ".$page." HTTP/1.0",
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: \"run\"",
"Content-length: ".strlen($xml_data),
"Authorization: Basic " . base64_encode($credentials)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);

Solution:
add this below
Find:
$html = file_get_contents_curl($url);
Add beow it:
//Change encoding to UTF-8 from ISO-8859-1
$html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $html);
