You are actually doing something like:

select translate(E'Herv\xc3\xa9',
E'\xc3\xa2\xc3\xa0\xc3\xa4\xc3\xa9\xc3\xa8\xc3\xaa\xc3\xab\xc3\xaf\xc3\xb6\xc3\xb4\xc3\xb9\xc3\xbc\xc3\xbb',
E'aaaeeeeioouuu');

Which apparently translates \xc3 -> a and \xa9 -> i. 

I don't know why it does that though. Maybe it's the server_encoding. What does SHOW server_encoding; tell you?
