Nah, it's not a problem with the Python version, it's the locale of
the build environment:

$ LC_ALL=C python2 ./Source/WebInspectorUI/Scripts/cssmin.py < ./Source/WebCore/xml/XMLViewer.css > /dev/null

$ LC_ALL=C python3 ./Source/WebInspectorUI/Scripts/cssmin.py < ./Source/WebCore/xml/XMLViewer.css > /dev/null
Traceback (most recent call last):
  File "./Source/WebInspectorUI/Scripts/cssmin.py", line 46, in <module>
  File "/usr/lib/python3.4/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 642: ordinal not in range(128)

So if the locale is set to ascii, then python 3 expects the standard
input to be ascii, and otherwise it complains.

We can tell people to use UTF-8 for building WebKit, but we can also
force the stdin enconding using this patch.
