My guess is that mutt looks at the locale environment (LANG and LC_*) to
set the encoding of the source data, and tries to recode it into one
of the encodings in send_charset.

If you _know_ your data is iso-8859-1 but your LANG etc. is something
else, try changing LANG locally in your driver script/program.

BTW, running mutt non-interactively has always seemed strange to me.
Why not use something simpler like mailx, or even /usr/sbin/sendmail?
