rmail-redecode-body
rmail-redecode-body is an interactive compiled Lisp function in `rmail.el
'.
(rmail-redecode-body CODING)
Decode the body of the current message using coding system CODING.
This is useful with mail messages that have malformed or missing
charset= headers.
This function assumes that the current message is already decoded
and displayed in the RMAIL buffer, but the coding system used to
decode it was incorrect. It then decodes the message again,
using the coding system CODING.
