I pass three variables through javacripting and these variable fetch from flash.

Code:
window.open("http://www.abc.com/postcomment.php?nID="+id + "&song_name=" +songname + "&artist_name=" +artistname);
Inside variable have Arabic character (UTF-8) and Url should like this:
http://www.abc.com/postcomment.php ... song_name=ويتمي ز ايو&artist_name =مزيج...
