Yes.  Of course.  It is one of these days were whatever i do
i stumble over errors in my own as well as in other peoples

  #?1|kent:tmp$ cat <<_EOT | iconv -f utf8 -tlatin1 | LC_ALL=C col -x
  one
  two
  three
  four
  five
  älter
  _EOT
  col: failed on line 11: Invalid or incomplete multibyte or wide character
  one
  two
  three
  four
  five

No fun for me today.
