Reading PDF, character problems

I am trying to use PurePDF to collect some information inside a PDF file, but cannot read PurePDF.

Whenever PurePDF tries to read any pdf file, it says it can't find its header, I tried debugging it and noticed that the string read by bytearray fits like Japanese characters! I tried changing the endian of my pdf bytearray before passing it to PurePDF, but it didn't change anything.

The pdf file is fine as I see the header "% PDF-" whenever I open it as text, but for some reason ActionScript is getting the wrong characters, so PurePDF just can't work at all.

Any ideas?

Thank.

Update: I'm not a bytearray expert, but I decided to talk to him and execute the code through the debugger and found out that he used readInt () to get characters, I just rewrote it with readByte () and now it reads PDF! I can still see if the functions will work ... Can someone with more low level programming explain to me what might be going on? I don't think the project is broken into svn

This is the code I used, I think it is quite simple:

private function loadPdf():void
    {
        var loader:URLLoader=new URLLoader();
        loader.dataFormat=URLLoaderDataFormat.BINARY;
        loader.addEventListener(Event.COMPLETE, onLoadComplete);
        loader.load(new URLRequest(PDF_FILE));
    }

protected function onLoadComplete(event:Event):void
    {
        var data:ByteArray = URLLoader(event.target).data as ByteArray;
        pdfReader = new PdfReader(data);
        pdfReader.readPdf();
    }
