The "0xe3bc74" looks like gibberish in any encoding I can think of.
What's the input file? Is it sanely encoded? Do you know what encoding
it is in?

If you really want to be encoding-agnostic and you do not care if you
get garbage data in your database that makes no sense and can never make
any sense, then you must ensure that your database is in the "C" locale
for LC_CTYPE and LC_COLLATE, and you must SET client_encoding =
"SQL_ASCII" when reading the data.

A suitable CREATE DATABASE command might be:

CREATE DATABASE garbage
TEMPLATE template0
ENCODING 'SQL_ASCII' LC_COLLATE 'C' LC_CTYPE 'C';

but I really don't think that's generally a good idea. Storing random
crap in text fields will cause you pain later. Better to either convert
the text to a sane encoding, store it as bytea if you want the raw
bytes, or reject it.
