1. Would like to try if you've ever successfully put Chinese characters
into the so-called "Postgresql" databases. Their four support
communities appear non-asian so far.

2. My problems is, although the 8.0 documentation (ch.14 pg. 292)
claims the conversion between EUC_TW and BIG5 is avalible, an actual
error message reveals it 's not supported, see below command and error
message:

代碼:

hongkong=# set client_encoding to 'BIG5';
ERROR: conversion between BIG5 and EUC_TW is not supported


Am I missing something?


3. Below lists the server_encoding is EUC_TW (the only Traditional
Chinese it supports on the server side):

代碼:

hongkong=# \l
List of databases
Name | Owner | Encoding
-----------+----------+-----------
hongkong | postgres | EUC_TW



4. fyi, sorry to dump you guy an "show all" screen (selected output):

代碼:

hongkong=# show all
hongkong-# ;
name | setting

-----------------------------------------------------------------------------------

.......
lc_collate | C
lc_ctype | C
lc_messages | C
lc_monetary | C
lc_numeric | C
lc_time | C
.....
syslog_facility | LOCAL0
syslog_ident | postgres
TimeZone | Hongkong
..
(139 rows)


cheers, thanks in advance.

There is a very larqe and active PG community in Japan.

Unfortunately, I'm no expert on Asian encodings, so I'm not sure I can
help further...

Strange. I have successfully set the client encoding to BIG5 with
PostgreSQL 8.0.3 on Linux.

$ psql euc_tw
Welcome to psql 8.0.3, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit

euc_tw=# \encoding
EUC_TW
euc_tw=# set client_encoding to 'BIG5';
SET

I suspect you have some problems with your PostgreSQL installation.

You're right about it. After a 8.0.3 re-installation, the issue seems
to have gone.

See screen output:

euc_tw=# \d contacts
Table "public.contacts"
Column | Type | Modifiers
--------+-----------------------+-----------
id | integer |
name | character varying(50) |

euc_tw=# insert into contacts values('1','\345\244\251\345\244\251');
INSERT 17235 1
euc_tw=# select * from contacts
euc_tw-# ;
id | name
----+--------
1 | ¤Ñ¤Ñ
(1 row)


Thanks for pinpointing the potential cause, so makes the trouble
shooting a lot easier.
