python - pdfminer/poppler - how to set encoding -

-

i have file, i.e. http://www.agfl.cs.ru.nl/papers/manual28.pdf (it's english)

pdfminer , poppler shows same result in parsed pages, like: ¾º¿  ÒÙ Öݸ ¾¼¼ Ⱥ ¾º ÂÙÒ ¸ ¾¼¼ ź Ë ÙØØ Ö¸ Ǻ Ë

it seems can't read font custom encodings. how specify it?

here's code samples:

# poppler input_filename = '/tmp/manual28.pdf' document = poppler.document_new_from_file('file://%s' %  urllib.pathname2url(os.path.abspath(input_filename)), none) n_pages = document.get_n_pages() in range(n_pages):     page = document.get_page(i)     print page.get_text()     # chardet.detect(page.get_text()) # utf8 time  # pdfminer def pdf_to_html(in_fp, out_fp, codec='utf-8', maxpages=0, pagenos=none, html=true):     rsrcmgr = pdfresourcemanager()     laparams = laparams()      if isinstance(in_fp, basestring):         in_fp = open(in_fp, 'rb')      if isinstance(out_fp, basestring):         out_fp = open(out_fp, 'wb')      if html:         device = htmlconverter(rsrcmgr, out_fp, codec=codec, laparams=laparams)     else:         device = textconverter(rsrcmgr, out_fp, codec=codec, laparams=laparams)      interpreter = pdfpageinterpreter(rsrcmgr, device)     page in pdfpage.get_pages(in_fp, pagenos, maxpages=maxpages):         interpreter.process_page(page)      in_fp.close()     device.close()     out_fp.close()

python - Subclassed QStyledItemDelegate ignores Stylesheet -

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
