Why this symbol is inserted in my downloaded file?

Hi. I download this xml file from my server with this code:

www = new WWW(URL_XML);
while( && www.error == null){
}

I have the same file in my Assets. When I comparing the files texts like:
if (www.text == XML_Languages.text)

The result is that the file arent the same, After searching I find tihs symbol difference in the files…See the attaceh image. Is the first symbol before <?xml…

This symbol only appear in downloaded file. In file from my asset there arent.

I try download manually from FileZilla and also not exist this symbol.

Any Help?

Thanks

I would guess, it’s a BOM.
