import urllib2, codecs, os

txt = urllib2.urlopen('http://www.unicode.org/udhr/d/udhr_bba.txt').read()
with codecs.open('test.txt','w','utf8') as fout:
  print>>fout, txt

print len(codecs.open('test.txt','r','utf8').readlines())
with codecs.open('test.txt','r','utf8') as fin:
  for _ in range(5): fin.readline()
  print len(fin.readlines())+5

os.remove('test.txt')
