Come risolvere la codifica in Python Mechanize?

Question

Ecco il codice di esempio:

from mechanize import Browser 

br = Browser() 
page = br.open('http://hunters.tclans.ru/news.php?readmore=2') 
br.form = br.forms().next() 
print br.form 

Il problema è che il ritorno del server codifica non corretta (windows-CP1251). Come posso impostare manualmente la codifica della pagina corrente in mechanize?

Errore:

Traceback (most recent call last):

LookupError: unknown encoding: windows-cp1251 

Answer 1

Risolto impostando

br._factory.encoding = enc 
br._factory._forms_factory.encoding = enc 
br._factory._links_factory._encoding = enc 

(non e i trattini bassi) dopo br.open()

Answer 2

Non so su Mechanize, ma si potrebbe incidere codecs di accettare i nomi di codifica sbagliata che hanno sia e 'cp' 'finestre':

>>> def fixcp(name): 
...  if name.lower().startswith('windows-cp'): 
...   try: 
...    return codecs.lookup(name[:8]+name[10:]) 
...   except LookupError: 
...    pass 
...  return None 
... 
>>> codecs.register(fixcp) 
>>> '\xcd\xe0\xef\xee\xec\xe8\xed\xe0\xe5\xec'.decode('windows-cp1251')
