Re: enhanced select-safe-coding-system

[Richard Stallman]

    I have recently posted a fairly simple patch that does that by slightly
    modifying the C code, so it's fast.  The only question is if such
    a functionality is good enough to efficiently implement Emacs-20's behavior
    (which was to highlight the offending chars, rather than just jump to the
    first one)

Showing the first one is better than nothing, so how about if you
install your patch now?  Then people can look at modifying it to
report more than just the first one.
