This seems to summarize only half of the problem. Mono's U+0000
quoting creates a string which is an invalid filename; PEP 383's
creates one which is an unsanctioned collection of code units. Neither
can be passed directly to the posix filesystem in question. I favor
PEP 383 because its Unicode strings can be usefully passed to most
APIs that would display it usefully. Mono's U+0000 probably truncates
most strings. And since such non-valid Unicode strings can occur on
the Windows filesystem, I don't find their use in PEP 383 to be a
flaw.
