PDF parser not working

[timnugent]

I tried the PDF download/parsing example here: http://www.clips.ua.ac.be/pages/pattern-web#pdf

But ran into this issue:

Python 2.7.6 (default, Mar 22 2014, 22:59:56) [GCC 4.8.2] on linux2 Type "help", "copyright", "credits" or "license" for more information.

from pattern.web import URL, PDF url = URL('http://www.clips.ua.ac.be/sites/default/files/ctrs-002_0.pdf') pdf = PDF(url.download()) Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/Pattern-2.6-py2.7.egg/pattern/web/init.py", line 3775, in init self.content = self._parse(path, format=output) File "/usr/local/lib/python2.7/dist-packages/Pattern-2.6-py2.7.egg/pattern/web/init.py", line 3790, in _parse raise PDFError(str(e)) pattern.web.PDFError: must be encoded string without NULL bytes, not str

Using latest version from Git under Ubuntu 14.04.

Cheers, Tim

@Tim, just do pdf = PDF(url.download(unicode=True)) the encoding is the issue here.

[timnugent]

That didn't solve it I'm afraid:

pattern.web.PDFError: must be encoded string without NULL bytes, not unicode

[Abhilash-D]

Oh. It worked for me after I made unicode=True. No idea what would be the issue then.

Hi, i get the same problem whit pdf, but the error is the next: "must be encoded string without NULL bytes, not unicode"
