The last time I tried to do this, I couldn't get w3m to properly
display some character sets, so I gave up trying with w3m as a
browser and wrote a script around "w3m -dump". From my mailcap
file:
text/html; w3m %s; nametemplate=%s.html
text/html; html2text %{charset} %s; \
nametemplate=%s.html; \
copiousoutput
The core of the html2text script is this:
charset="$1"
# Implement the equivalent of mutt's charset-hook for these:
#
# charset-hook ^us-ascii$ windows-1252
# charset-hook ^iso-8859-1$ windows-1252
#
case $charset in
us-ascii) charset=windows-1252;;
US-ASCII) charset=windows-1252;;
iso-8859-1) charset=windows-1252;;
ISO-8859-1) charset=windows-1252;;
ks_c_5601-1987) charset=gb2312;;
KS_C_5601-1987) charset=gb2312;;
esac
file="$2"
w3m_args="-dump -T text/html -o frame=0 -o meta_refresh=0 -o auto_image=0
-I $charset -O $charset"
w3m $w3m_args $file |
iconv -c -f $charset -t ISO-8859-1//TRANSLIT
Note that rather than have w3m perform the charset conversion, I
told w3m to leave the charset unchanged and instead let iconv do the
conversion. This is admittedly a hack, but it has worked well for
displaying HTML mutt's pager.
The //TRANSLIT suffix is important for me to be able to display M$
characters in my environment, and as I recall, w3m doesn't
understand //TRANSLIT.
