yes, i would not have been surprised. because it's kind-of expected when
dealing with input, that malformed input raises an unicode-exception.
and i would also expect, that if os.listdir completed without raising an
exception, then the returned data is correct.

depends on the application. in the one where it happened i would just
display an error message, and tell the admins to check the
(in other ones, where it's not critical to get the correct name, i would
probably just convert the text to unicode using the "replace" behavior)
what about using flags similar to how unicode() works? strict, ignore,
replace and maybe keep-as-bytestring.
i know it's not the most elegant, but it would solve most of the
use-cases imho (at least my use-cases).
