Or, you can cheat. If you are reading from a file, you can make set
it up so any string that you read from the file automatically gets
converted from its encoding to another encoding. You don't even have
to be aware of the fact that a regular string has to be converted into
a unicode string before it can be converted to a regular string with a
different encoding. Check out the codecs module and the EncodedFile()
s = 'he Company\xef\xbf\xbds ticker'
f = open('data2.txt', 'w')
f = open('data2.txt')
f_special = codecs.EncodedFile(f, 'utf-8', 'iso8859_15') #file, new
encoding, file's encoding
print f_special.read() #If your display device understands utf-8, you
will see the troublesome character displayed.
#Are you sure that character is legitimate?
