or... 
$str =~ s/([\xA0-\xFF])/{$iso8859{$1} ? $iso8859{$1} : $1 }/ge;

This one would be useful if you only have iso8859 values for *some* hex characters. You can do without that block on the right side (and the trailing /e as well) if you make sure that every value in the range given on the left side is defined in the hash and has a value. For example: 
$str =~ s/([\xA0-\xA6])/$iso8859{$1}/g;
