What happens if a character is broken across a buffer boundary? e.g. if
someone tries to read or write one byte at a time (you can't do a
partial read of zero bytes, there's no way to distinguish that from an
EOF.)
Is there going to be a higher-level text I/O class that bypasses the
UTF-8 encoding step when the underlying bytes stream is a console? What
if we did that but left the encoding as mbcs? I.e. the console is text
stream that can magically handle characters that aren't representable in
its encoding. Note that if anything does os.read/write to the console's
file descriptors, they're gonna get MBCS and there's nothing we can do
about it.
