You misunderstand meaning of *substitution-char*. This is the character that will be used as a substitution for all badly encoded characters.
Thus, this example is equvalent to (setq flexi-streams::*provide-use-value-restart* t) (setf flexi-streams::*SUBSTITUTION-CHAR* ?)
You will have ? instead of any wrong character.
I.e. you can use the whatever mechanism you like: *substitution-char* for most cases or use-value-restart if you whant more control (for example you what to use ? as a substitution for even wrong byte sequence, and * for odd wrong byte sequence; count encoding errors, log them into file or something)
Read the docs, http://weitz.de/flexi-streams/

Hi, Jeff.
"Signaling an error" means in this case that work can be proceeded.
(setq *provide-use-value-restart* t)
(handler-bind ((flexi-stream-encoding-error (lambda (condition)
(use-value \?)))) (drakma:http-request("http://bad-host/bad-page.html")))This is example from flexi-stream documentation.
You can easy get "the best approximation of the content" using drakma, but with more control. So it is unclear to my, what problems you have.

Hi Anton,
Thanks for the help. Will the example above work for any bad charactor, or only the one set by
(setf flexi-streams::*SUBSTITUTION-CHAR* (code-char #xA0))
The only example I've run across is the site I mentioned, but it seems like the possibilities for bad html are endless.
