This is a duplicate of #10801, issue fixed in Python 3.2 or later by 
33543b4e0e5d. Should we backport the fix to Python 3.1, or you can upgrade to 
Python 3.2?

Output with Python 3.2: ╕┤╝■ test.txt.

2011-05-12 Thread Amaury Forgeot d'Arc 

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:

But according to the initial report, 3.2 does not give the expected behavior. 
This zip file actually stores the filename encoded with cp932, which is 
incorrect according to the specifications of the ZIP format (only cp437 and 
utf8 are valid)

See issue10614 for a possible solution: allow users to specify an alternate 
encoding to handle such invalid files.

STINNER Victor victor.stin...@haypocalc.com added the comment:

Oh, right.

Note: the encoding looks to be GBK, not CP932:

 '\u590d\u4ef6'.encode('gbk')
b'\xb8\xb4\xbc\xfe'
 '\u590d\u4ef6'.encode('gbk').decode('cp437')
'╕┤╝■'
 '\u590d\u4ef6'.encode('cp932')
...
UnicodeEncodeError: 'cp932' codec can't encode character '\u590d' ...

2011-05-10 Thread yaoyu 

New submission from yaoyu yao...@126.com:

Python 3, ZipFile Bug In Chinese:
1. In Python3.1.3 can't extract 复件 test.txt from test.zip
╕┤╝■ test.txt
Traceback (most recent call last):
  File C:\Temp\PythonZipTest\pythonzip.py, line 14, in module
main()
  File C:\Temp\PythonZipTest\pythonzip.py, line 11, in main
z.extract(z.namelist()[0])
  File c:\python31\lib\zipfile.py, line 980, in extract
return self._extract_member(member, path, pwd)
  File c:\python31\lib\zipfile.py, line 1023, in _extract_member
source = self.open(member, pwd=pwd)
  File c:\python31\lib\zipfile.py, line 928, in open
% (zinfo.orig_filename, fname))
zipfile.BadZipfile: File name in directory '╕┤╝■ test.txt' and header 
b'\xb8\xb4\xbc\xfe test.txt' differ.

2.  In Python3.2 extract 复件 test.txt from test.zip uncorrect
  It extract the file as ╕┤╝■ test.txt

3. In Python 2.7.1, It's OK!
