Problematic filename - is it latin? how do i convert it to ansii?

Question

when retrieving a file to save it from gmail, I get the following error message:

Traceback (most recent call last):
  File "C:\a.py", line 32, in on_hello
    if getmail(self):
  File "C:\a.py", line 96, in getmail
    fp = open(att_path, 'wb')
IOError: [Errno 22] invalid mode ('wb') or filename: '.\\=?iso-8859-1?Q?CC_GM=5F
Est=E1vel.xlsx?='

Now, I suspect that =?iso-8859-1?Q?CC_GM=5FEst=E1vel.xlsx?= is the problem, how can I convert it to ansii? I tried using all sorts of .decode and .encode combinations with no success.

Thanks

That uses the [Encoded-Word](https://en.wikipedia.org/wiki/MIME#Encoded-Word) encoding. This encoding has no business existing anywhere *except* in MIME Headers. — Joachim Sauer, Jan 21 '13 at 16:03

You are looking at a Quoted-printable encoding (a variant as used in MIME email headers, called encoded-word). The email.header module handles this for you:

>>> from email.header import decode_header
>>> for part in decode_header('=?iso-8859-1?Q?CC_GM=5FEst=E1vel.xlsx?='):
...     value = str(*part)
...     print(value)
...

That's a MIME-encoded email header.

You should* be able to use something in here, perhaps decode:

First of all, iso-8859-1 has a number of characters that ansi does not have see this. Are you sure that you can safely ignore all those characters in your situation? One other idea which I would tend more towards would be an iso-8859-1, to (some flavour of Unicode, i.e. utf8, utf16, etc). Here is an answer to your question from [SO] which will do the conversion2. CHEERS!
