UnicodeDecodeError in unpack_archive when extract_dir is unicode on Python 2

[cjw296]

I see 25.1.2 was release today, and I've just had nightly builds of one of my packages fail as follows:

Installing docs.
Getting distribution for 'sphinx'.

An error occurred when trying to install Sphinx 1.4.5. Look above this message for any errors that were output by easy_install.
While:
  Installing docs.
  Getting distribution for 'sphinx'.
Error: Couldn't install: Sphinx 1.4.5

The full log is here: https://travis-ci.org/cjw296/nose_fixes/jobs/149012793

Any idea when this could be fixed?

I saw this issue as well.

Here are the changes since 25.1.1. Given the nature of the error and the stack trace that the issue arises from the fix for #704.

[jaraco]

I'm able to replicate the failure with easy_install sphinx.

$ ~/.virtualenvs/issue709/bin/python -m easy_install sphinx

[jaraco]

Oh awesome. All but the Python 3.5 unicode tests failed.

[cjw296]

Any chance the fix for #704 could be reverted until it can be corrected?

[sileht]

This have to be revert it also breaks any C extension installed with easy_install (or via setup_requires) see: #712
