   You can correct the problem by decoding the message again using the
 right coding system, if you can figure out or guess which one is
 right.  To do this, invoke the @kbd{M-x rmail-redecode-body} command.

-  Decoding and encoding using the wrong coding system is lossless for
-most encodings, in particular with 8-bit encodings such as iso-8859 or
-koi8.  So, if the initial attempt to redecode the message didn't
-result in a legible text, you can try other coding systems until you

-  With some coding systems, notably those from the iso-2022 family,

-again won't bring back the original incoming text.  In such a case,
