From Jaume's example:

\361 == 0xf1. UTF-8 assumes that:

     if (the first byte) & 0xe0 == 0xe0, then the letter consists of 3

So PostgreSQL believes that "a|" is one UTF-8 letter and eat up

My guess is Jaume made an UNICODE database but provided it ISO 8859-1
or that kind of single-byte latin encoding data.

I'm wondering why so many people are using UTF-8 database even he does
not understand what UTF-8 is:-) I hope 7.1 would solve this kind of
confusion by enabling an automatic encoding conversion between UTF-8
and others.
