The coding cookie only affects unicode string constants in the source code,
it doesn't change how the unicode data coming from BeautifulSoup is handled.
As I suspected in my other post you have to convert your data to a specific
encoding (I use UTF-8 below) before you can write it to a file:
import urllib2
import codecs
from BeautifulSoup import BeautifulSoup
html = urllib2.urlopen(
'http://www.kaasogmulvad.dk/unv/python/tabeltest.htm').read()
soup = BeautifulSoup(html)
with codecs.open('tabeltest.txt', "w", encoding="utf-8") as f:
rows = soup.findAll('tr')
for tr in rows:
cols = tr.findAll('td')
print >> f, "#".join(col.string for col in cols)
The with statement implicitly closes the file, so you can avoid f.close() at
the end of the script.
