Analysis from Phillip J. Eby:

That's not the problem, it's that the code that writes the PKG-INFO file 
doesn't handle Unicode.  See 
distutils.dist.DistributionMetadata.write_pkg_info().  It needs to use a 
file with encoding support, if it's doing unicode

However, there's currently no standard, as far as I know, for what encoding 
the PKG-INFO file should use.  Meanwhile, the 'register' command accepts 
Unicode, but is broken in handling it.

Essentially, the problem is that Python 2.5 broke this by adding a unicode 
*requirement* to the "register" command.  Previously, register simply sent 
whatever you gave it, and the PKG-INFO writing code still 
does.  Unfortunately, this means that there is no longer any one value that 
you can use for your name that will be accepted by both "register" and 
anything that writes a PKG-INFO file.

Both register and write_pkg_info() are arguably broken here, and should be 
able to work with either strings or unicode, and degrade gracefully in the 
event of non-ASCII characters in a string.  (Because even though "register" 
is only run by the package's author, users may run other commands that 
require a PKG-INFO, so a package prepared using Python <2.5 must still be 
usable with Python 2.5 distutils, and Python <2.5 allows 8-bit maintainer 

Unfortunately, this isn't fixable until there's a new 2.5.x release.  For 
previous Python versions, both register and write_pkg_info() accepted 8-bit 
strings and passed them on as-is, so the only workaround for this issue at 
the moment is to revert to Python 2.4 or less.
