No it doesn't. It does transcode without throwing exceptions. On POSIX.
(On Windows? I doubt it - windows isn't using an 8-bit scheme. I
believe.) But it utter destorys any hope of working in any other locale
nicely. The PEP lets you work losslessly in other locales.
It _may_ require some app care for particular very weird strings
that don't come from the filesystem, but as far as I can see only in
circumstances where such care would be needed anyway i.e. you've got to
do special stuff for weirdness in the first place. Weird == "ill-formed
unicode string" here.
