Thanks, I'll take a look.

In the meantime I came up with a quick and dirty solution to see
how useful a similar feature could be in standard isearch.

It is a simple advice which automatically deletes non matching characters
immediately, so it does not allow building up bad characters
in the search string:


(defadvice isearch-search-and-update
   (after isearch-search-and-update-ignore-bad-chars activate)
  (unless isearch-success
    (push 127 unread-command-events)))


I tried a few searches and it seems useful. Why is the default
implementation leaves bad characters in the search string at all? It is not
very useful, because then you must delete them manually.
