That is the right way.

Do you have a reason to believe `file' more than you believe Emacs?
That is, is it possible that `file' lies?  Can you find a character in
the file after translation that is not Latin-1, and if you can, what
is that character?

One possibility is that you have in that file a character whose code
is outside the valid range of Latin-1 codepoints.  But that's a wild
guess, you need to find such a character and type "C-u C-x =" with the
cursor on it, to see what it is.
