[ summary for the w3m devels: some html page includes the string

Thanks David.

What I don't understand here is why w3m doesn't display
^M (or, perhaps, something else) in xterm when the page explicitly
asks to do so.

Some of the rendering is done by w3m and some within emacs.  The
translation of entities to characters is one of the things that
happens in emacs.

How do you think should emacs-w3m render a carriage return?
I consider ^M to be garbage in the rendered html so it should not be
displayed by default unless, of course, specifically requested.

If the html source includes the entity "&#13;" it explicitly
requested the display of a carriage return (whatever this means), at
least in my opinion.  But again, this might be some html "feature" I
don't know about.

IMHO the right thing to do here is to read up in the HTML specs how
whitespaces encoded with html entities should be treated.

Could it be the HTML file contains _both_, line-endings indicated by CR as well as some by newline or CR/LF? So maybe Emacs is somehow tricked to believe it's displaying a -unix or -dos encoded file and rejects to recognise the discrete ^Ms as newlines, while the terminal unconditionally displays anything looking like it might be a newline as such.

Just a thought.

Have fun
