Re: Invalid EUC_TW character sequence found

Hi Tatsuoi,

Thanks for your quick response. Actually I tried both way (1. dump and
restore, 2. create a new database in version 7.2.1) but in vain.

The first way is to dump a database from 7.0.2 database containing EUC_TW
data

List of databases
Database | Owner | Encoding
---------------+----------+----------
AccessControl | postgres | EUC_TW

The old database was created by the EUC_TW encoding. It works fine with the
chinese characters for version 7.0.2. However when I follow the
instruction to do the upgrade with restore to my redhat 6.1, it gives error
such as Invalid EUC_TW character sequence found.

Then I search for the news group, with "Invalid EUC_TW character sequence
found", a guy named Gordon Luk has the same problem as me. Actually he is
my friend, originally I thought it may be the problem of Redhat 7.3 with
postgresql pre-installed. So I decided to try with the tar file and did the
installation to Redhat 6.1.

The second way to confirm version 7.2.1 can not accept chinese input is to
create a new database with the following command:

CREATE DATABASE "test" WITH ENCODING = 'EUC_TW';

then create table site (name varchar(50)); and insert data directly with
pgAdmin II, it gives error as follows:

2002-06-26 09:22:28 - SQL (test): INSERT INTO "site" ("name") VALUES
('­»´ä¦r')

If the coming version can not support chinese, it may be a big problem for a
lot of people. As a database user myself, we do not have much knowledge
about those encoding stuff. And we have to rely on you guys. You guys have
already done a lot of good things to the open source. Just keep on
searching the best.

Thanks!
