> OK, here is what I see using the current Debian versions of these packages.

Thank you for your report.

There is a possibility for this problem to occur with emacs23 or
later. A problem occurs for the width of the box drawing
character changed. So, calculation of string-width goes miss,
and it becomes for that like your image.


For example 
(BOX DRAWINGS LIGHT VERTICAL AND HORIZONTAL, #x253c)
・Emacs22.3
(char-width (make-char 'mule-unicode-2500-33ff 32 92)) => 1

・Emacs23.1
(char-width (make-char 'mule-unicode-2500-33ff 32 92)) => 2


It is very difficult to correct this problem on all
emacsen. Therefore, please use emacs-w3m because of the
following settings. 

(setq w3m-use-symbol nil)

This change was commited to CVS HEAD of emacs-w3m.

TNX.
