As quoted above, deprecation of the bytes version of the API sounds fine to me, but isn't this going to run into the usual objections from the "we need bytes for efficiency" crowd?  It's OK with me to say "in this restricted area you must convert to Unicode", but is that going to fly with that constituency? I don't think this "we need bytes for efficiency" crowd actually exists.

I think that crowd does exist, but I've only ever seen them complain about URLs and other wire protocols (where turnaround time can matter a lot in terms of responsiveness of network applications for short requests, and encode()/decode() cycles can really add up). Filesystem access is dominated by I/O time, and there's often going to be some encoding or decoding going anyway (since the app and the filesystem have to get the data into a common format).

Cheers, Nick.
