Bad.  OK, here is my task: I have a C string in the sources, possibly
containing encoded characters, like

        "foo bla \xc2\xa9",

the last thing being the UTF-8 copyright characters.  I want to
decode the string (can do that) _and_ know where particular
characters begin. Currently I set text property `point' on character
beginnings, but `decode-coding-string' eats them :(  Can anyone see a
different solution, maybe ugly if nothing else?  (Except that custom
implementation of `decode-coding-string' doesn't count as a solution
;)
