Looks okay to me. I thought your test string might be a bit too easy (didn't cover enough possible trouble makers), and I wondered whether putting "decode_entities" before the cp1252 lookup might cause a problem (because when you decode entities like "Ñ" ("Ñ"), you get utf8 byte sequences that include bytes like 0x91, which might get mistreated by the cp1252_lookup).

But then I tried it out, adding "Ñ" and "Ò" to the test string, and they magically came out right: 

...
my $str = join('',
  chr(0x93), 'double', chr(0x94), ' Ñ Ò ', 
  chr(0x201C), 'double', chr(0x201D),
  '‘single’'
);
...
output:

“double” Ñ Ò “double”‘sing
+le’

which looks like what you would want to get.

Update: based on your reply, I figured it might make sense to try numeric character entities above 0xff -- e.g. Ǒ and ǒ (when converted to utf8, these have 0x91 and 0x92 as the second byte). It still works the way you would want, converting them correctly to hex-coded numeric entities (Ǒ and ǒ, upper and lower case letter o with caron, respectively).
