How can I encode and decode urls from IDN in php?

Question

im make a website for verification, registration, etc. domains, I have to make it compatible with IDN. Right now I have something like this:

echo $domain;       
$domain = idn_to_ascii($domain);
echo $domain;
$domain = idn_to_utf8($domain);
echo $domain;

and im get the following:

testing123ásd123 x - testing123sd123-WJB testing123ĂĄsd123

since you can see that the decoded string does not match the original, I also tried using the http://phlymail.com/en/downloads/idna/download/ class to do this and im getting the same results

I tried using:

$charset="UTF-8";
echo $domain;       
$domain = idn_to_ascii($domain, $charset);
echo $domain;
$domain = idn_to_utf8($domain);
echo $domain;

and I got exactly the same (except that the encoded string is slightly different)

any ideas?
