I've taken your example, saved the XML and PHP files to disk, changed =20= the URL for generateModel() to the filename, called the page from the =20= browser, and ithe bulgarian fragment is displayed correctly. (But the =20= bulgarian bit in the file that you copy&pasted into the email is =20 displayed as gibberish by my email client, so I copy&pasted it from =20 your original email where it appeared fine, and saved the file as =20 UTF-8. Not sure if this is related to the problem or just email =20 misbehaving.) Can you please verify that your version of the XML file is really =20 UTF-8 encoded? Or you could send it to me by *attaching* it to the =20 email, then I can check. Also, can you put the script onto a webserver where we can se it?
