summary:
(Merge 3.3) Issue #17429: platform.linux_distribution() now decodes files from
the UTF-8 encoding with the surrogateescape error handler, instead of decoding
from the locale encoding in strict mode. It fixes the function on Fedora 19
which is probably the first major distribution release with a non-ASCII name.
Patch written by Toshio Kuratomi.
