Hi, all !

I can't convert with convert(bytea, name, name)::bytea from 'iso-8859-5'
to 'windows-1251' or any other cyrillic 8-bit encoding.

seb=> show client_encoding ;
client_encoding
-----------------
UTF8

seb=> show server_encoding;
server_encoding
-----------------
UTF8

seb=> select version();
version
----------------------------------------------------------------------------------------
PostgreSQL 8.3.0 on i486-pc-linux-gnu, compiled by GCC cc (GCC) 4.2.3 (Debian
4.2.3-1)

lc_ctype | ru_RU.UTF-8
lc_messages | ru_RU.UTF-8
lc_monetary | ru_RU.UTF-8
lc_numeric | ru_RU.UTF-8
lc_time | ru_RU.UTF-8

seb=> select
convert(convert('абвгдеёжзийклмноР¿Ñ€Ñ�туфхцчшщъыьÑ�ÑŽÑ�Ð�БВГДЕÐ�ЖР—ИЙКЛМÐ�ОПÐ*СТУФХЦЧШЩЪЫЬÐ*ЮЯ' , 'utf-8', 'iso-8859-5'), 'iso-8859-5', 'windows-1251');
ERROR: character 0xf1 of encoding "ISO_8859_5" has no equivalent
in "MULE_INTERNAL"

At first - i am convert my console locale encoding (ru_RU.UTF-8) to iso-8859-5
(cyrillic 8-bit character encoding) and second convert is for show problem.

windows-1251 - is other cyrillic 8-bit character encoding, convert to koi8-r
also not work.

i am write output of convert(..., 'utf-8', 'iso-8859-5') into file and readit
with: iconv -f iso-8859-5 -- all chars readed ok. (see progs in attach)

convert(..., 'iso-8859-5', 'utf-8') looking good, i am check it like this:
seb=> set standard_conforming_strings TO on; --- do not escape bytea
SET
seb=> select
convert('\320\321\322\323\324\325\361\326\327\330\ 331\332\333\334\335\336\337\340\341\342\343\344\34 5\346\347\350\351\352\353\354\355\356\357\260\261\ 262\263\264\265\241\266\267\270\271\272\273\274\27 5\276\277\300\301\302\303\304\305\306\307\310\311\ 312\313\314\315\316\317', 'iso-8859-5', 'utf-8');
