No.  Auto-save files are encoded using Emacs's internal coding-system,
which makes the operation a lot more reliable and efficient (no need to
worry about the case where some char(s) can't be encoded, for example).

Just open the file with the right coding-system (typically, opening
"myfile" and then hitting M-x recover-this-file RET should do the
trick).

     - Is there a systematic way to convert #myfile# to iso-latin-9 (or
iso-latin-1) code, other than painstakingly searching and replacing
offending chars ?

#myfile# c&n be opened in this way but cannot be saved, as the coding 
system is not recognized.

Yes.  

   C-x RET c emacs-internal RET C-x C-f #myfile# RET
   C-x RET f latin-9 RET
   C-x C-s

You should open myfile, not #myfile#.  Then Emacs will automatically
notice that the auto-save file for it exists, and offer to recover it.

i thought emacs 23/24 uses a superset of utf-8 as internal encoding?
so that i thought those #autosave# files are encoded in utf-8, and as
long as one open them with utf-8 decoding all chars would show. Is
this not correct?

(i turned of auto-save and auto backup few years ago)

It does.

Not 100%, because it's a superset.  That is, there could be codes
there that UTF-8 will fail to decode.
