I noticed a while ago after some updates that some web sites stopped rendering correctly and produced binary-looking buffers. I didn't resolve this. A little later another person mentioned the same thing in the emacs help mailing list. But some others don't have the problem. I tracked it down and it appears to be that emacs-w3m doesn't have a "brotli" handler for brotli web page compression, as used by slashdot, duckduckgo, and others. Strangely this only seems to affect the later versions of the w3m command; earlier versions seem okay although I can't be more specific about which versions.

I added two lines of code that for me and the other user resolve the problem.  The patch requires that the "brotli" command be in the command path.  I don't check for this.  I didn't generate a diff but the following in w3m.el should be hopefully clear enough.

defcustom w3m-decoder-alist should add this line to the list of types

    (br "brotli" ("-d"))

defconst w3m-encoding-alist should add this line to the list of types

		     (br . ("br"))

I hope this is of some use.
