[FEATURE REQUEST] select encoding for logs reader

Hi all
I have a proposition of a new feature: select of encoding which is used
by logs reader in server status window. It looks like pgAdmin assumes UTF8,
so sometimes gives an error.
It is possible to read files with different encoding via postgres:
eg:
SELECT convert_from(pg_read_binary_file('pg_log/postgresql-2012-12-07_000000.log',
0, 2000), 'WIN1250');

this is based on my post on pg_general list (
http://archives.postgresql.org/pgsql-general/2012-12/msg00164.php)

Thanks & Regards,
Bartek
