convert function

Hi all

I have problem with "convert" function. Previous behaviour was
SELECT convert('ján', 'UNICODE', 'SQL_ASCII');
=======================================
jan

In postgresql 8.3 is quite new behaviour.
SELECT convert('ján', 'UNICODE', 'SQL_ASCII');
======================================
"j\241n"

This, drives me crazy. I mean, this is not useable for non english
country. I don't need convert to \241 characters. I understand that
someone need this behavour. But there should be possibility switch to
"normal" behaviour.
