I know I keep flipflopping on this one, but the more I think about it the more I believe it is better to drop those names than to raise an exception. Otherwise a "naive" program that happens to use os.listdir() can be rendered completely useless by a single non-UTF-8 filename. Consider the use of os.listdir() by the glob module. If I am globbing for *.py, why should the presence of a file named b'\xff' cause it to fail? To avoid silent skipping, is it possible to drop 'unreadable' names, issue a warning (instead of exception), and continue to completion? "Warning: unreadable filename skipped; see PyWiki/UnreadableFilenames"

That would be annoying as hell in most cases.

I consider the dropping of unreadable names similar to the suppression of "hidden" files by various operating systems.
