Punycode converter not working on ONE page - why?

I have another strange problem. Since I work a lot with URLs

PHP Code:


		
			
include_once('idna_convert.class.php');
$IDN = new idna_convert();
   
$feeder = array("glühwein.dk","你好吗.com","madrid.com","zürich.eu","hallo.de");

foreach( $feeder as $key => $value )
{

echo $value."<br>";
$url = $IDN->encode($value);

echo $url."<p>";

}

/*
Output:
glühwein.dk
xn--glhwein-o2a.dk

你好吗.com
xn--6qqu8ipsf.com

madrid.com
madrid.com

zürich.eu
xn--zrich-kva.eu

hallo.de
hallo.de
*/

The sample page outputs exactly as above. However, in my 'real' page it works perfectly only on not alphanumeric URLs (Chinese, Japanese) - but not on URLs with ü , ö etc. Could it be performance related?

Any clue why that is?

PS: I am on PHP 5.3.1

Simple: Domain zürich.eu (or xn--zrich-kva.eu) isn't available at all.

Just enter those 4 in your browser. All of them work, apart from zürich.eu or xn--zrich-kva.eu.

Punycode is simple converting a string with special characters into a domain format. It does not have to an existing URL.

I am still totally puzzled. I put the code from the top into the page that gives me trouble - and the top parts works.

Japanese works, Chinese works, ä ü ö do NOT work, but ő works, but ñ does not. It works when I string them up in an array and decode them in a FOREACH loop. I can add a variable with a value into the Array. But when I put the same url into a variable (not array!) and then into the test array it will not work.

I got already a new idna_convert.class.php - same issue.

PS: Same error with PHP 5.4.7

I still can't solve this problem. I presume it's related to the charcater encoding. All problem domain names are in ASCII format. Even though the original HTML source format is UTF-8.

I presume the output from preg_match_all is in ASCII - now need to check either how to convert it back, or how to make preg_match_all output UTF-8.

After it is ASCII the data is extremely resistant to changes and I didn't manage you to get it back to UTF-8. I don't understand why utf8_encode() or mb_convert_encoding() fail to work.

Solved! This REALLY took me some time!

I tried to work it via mySQL and noted that whatever I try, data gets input as i.e. solglasögon.net instead of solglasögon.net

I then did a try and put this before the string:

PHP Code:


		
			
$value = str_replace("&amp;#246;","ö",$value);  // except the amp;

and it worked according plan!

Not to do a str_replace() for every special character I did:

PHP Code:


		
			
$value = html_entity_decode($value, ENT_COMPAT, "UTF-8");
