possible bug in quoted-printable-decode region

[Uwe Brauer]

Hi

(If needed I can provide a bug report).

Maybe I am missing something elementary here. I came across with a file
which still had quoted printable encoding like this 

Buenas d=C3=ADas:


So I used 
(quoted-printable-decode-region (region-beginning) (region-end) nil)

But I obtained the following 

Buenas d­as:

Not sure who these characters will be send so I write them literally 

Buedas d\303\255as:

Which looks to like some old pre uni code chars.

What went wrong?

Regards
