Package: mpack Version: 1.6-8.1 File: /usr/bin/munpack Always get rid of CR at the ends of lines, $ perl -pwle 's/\r$//;' k.mhtml > ku.mhtml $ file k* k.mhtml: news or mail, ASCII text, with CRLF line terminators ku.mhtml: news or mail, ASCII text
Or else when you give such a file to mumpack -t, you will get embedded 0xFF's! (Seen when unpacking quoted-printable. Didn't test unpacking Base64.)
