Correctly fold unknown-8bit originating from encoded words. ( #142517 )
...
The unknown-8bit trick was designed to deal with unknown bytes in an
ASCII message, and it works fine for that. However, I also tried to
extend it to handle bytes that can't be decoded using the charset
specified in an encoded word, and there it fails because there can be
other non-ASCII characters that were *successfully* decoded. The fix is
simple: do the unknown-8bit encoding using the utf-8 codec. This is
especially appropriate since anyone trying to do recovery on an unknown
byte string will probably attempt utf-8 first.

RDM: per AZero13's research the 'x' option did not exist when this code was written, This
modernization can thus drop the fd trick in _create_carefully and just use open with 'x' to achieve the same goal more securely.
