I ran into this recently myself with a project to insert E-mail messages into a PostgreSQL database. I solved it like so: 

 
use utf8; 
use Encode; 
my $possibly_bad_utf8_data = get_data(); 
my $good_data = encode( "UTF-8", $possibly_bad_utf8_data );

[download]

The capitalization of the UTF-8 in the call to encode() is important, it tells encode to be "strict" about the UTF-8. It turns out use utf8; isn't 100% strict and hence can't be inserted into a strict mode PostgreSQL database.

Hope this helps.
