[New-bugs-announce] [issue2660] 2to3 throws a utf8 decode error on a iso-8859-1 string

New submission from Brandon Ehle <azverkan at gmail.com>:

While running the 2to3 script on the scons codebase, I ran into an
UnicodeDecodeError.

Attached is just the portion of the script that causes the error.

2to3 throws an error on the string regardless of whether the unicode
string literal is prepended on the front.
