I'd tend to agree. ENCODE_UTF_8 is used for things where we *really*
want the output to be proper utf-8, so any char outside of utf-8
(e.g. an eight-bit char) should result in something else than a raw byte
in the output. This is contrary to what we do for utf-8 files, where we
output eight-bit chars as raw bytes (because any sequence of bytes
that's not valid utf-8 in the input leads to such eight-bit chars in
the buffer, so outputting them as raw bytes is used to preserve the
file unchanged when saved).
