The html data passed to w3m should be in the raw (binary) form.

In that case, w3m doesn't work on the same condition as when
emacs-w3m is used for Wanderlust to display html messages.
Although it might be able to reproduce the same trouble even
with that, emacs-w3m runs w3m with the -halfdump option then,
and the data that w3m returns are not human-readable.

Well, a list of arguments that passed to w3m is rather
complicated.  It will be the one to which the values of
`w3m-halfdump-command-arguments' and
`w3m-halfdump-command-common-arguments' and image options are
merged, but will vary according to the system and user's
preferences.  For instance:

-halfdump -o ext_halfdump=1 -o strict_iso2022=0 -o fix_width_conv=1-o\
use_jisx0201=0 -o ucs_conv=1 -I UTF-8 -O UTF-8

The most easy way (I think) to extract data and to know the
arguments is to run edebug on Emacs.
