New submission from Zooko O'Whielacronx <zooko at zooko.com>:

A user of Tahoe-LAFS encountered an error in which pyOpenSSL emitted:

exceptions.UnicodeDecodeError: 'utf8' codec can't decode bytes in position 0-5:
unsupported Unicode code range

It took some effort on the part of the user and the Tahoe-LAFS devs to delve
into the code and figure out how an invalid string got into a certificate inside
pyOpenSSL.  Eventually the user (David Abrahams) figured out that the issue was
this one:

He had installed a pyOpenSSL egg which had been built with UCS4, but his Python
interpreter was UCS2.  According to the thread linked above, the best way to fix
this is for distutils get_platform() to include the unicode variant in its
output, and then for setuptools to test the compatibility of that field when
choosing an egg.  Is that right?

What's the next step?
