It's because vim isn't *told* what character set the input file will
be; it has to guess. Mutt is handing it a UTF-8 file (because mutt
converts mail messages into whatever the local terminal character set
is before handing it to any other program (such as vim), for obvious
reasons). In UTF-8, the á character is represented as a two-byte
character: 0xc3 0xa1. However, your vim is assuming that input files
are in ISO-8859-1, and both of those bytes are valid ISO-8859-1
characters (this is the fundamentally impossible problem of
determining character set from unidentified byte streams). As you
might imagine, 0xc3 is Â, and 0xa1 is ¡.
This is what I have in my vimrc to handle this:
if has("multi_byte")
set encoding=utf-8
if $LANG !~ '\(UTF\|utf\)-\?8' && $LC_CTYPE !~ '\(UTF\|utf\)-\?8'
" Note that this only works if your shell GUARANTEES that
" either LANG or LC_CTYPE will be set correctly (as mine
" does). If not, it would be useful to do more thorough
" terminal detection here... but you really should make
" sure that LANG and/or LC_CTYPE is set correctly.
set termencoding=latin1
endif
