[New-bugs-announce] [issue13639] UnicodeDecodeError when creating tar.gz with unicode name

[Jason R. Coombs]

New submission from Jason R. Coombs <jaraco at jaraco.com>:

python -c "import tarfile; tarfile.open(u'hello.tar.gz', 'w|gz')"

produces

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\jaraco\projects\public\cpython\Lib\tarfile.py", line 1687, in open

    self.__write(self.name + NUL)
  File "C:\Users\jaraco\projects\public\cpython\Lib\tarfile.py", line 475, in __write
    self.buf += s
UnicodeDecodeError: 'ascii' codec can't decode byte 0x8b in position 1: ordinal not in range(128)


Remove the compression ('|gz') or remove the unicode name or run under Python 3 and the command completes without error.

The error does not occur under Python 3 (even with non-ascii characters), so it should be possible to create a tarfile with a unicode filename on Python 2.7.

This failure is the underlying cause of #11638.
