Hi,
Tip:
To identify what encoding you enter in the psql command interpreter:
1) Open a file with vim
2) Type in you SQL or copy/paste
3) Save the file and quit vim
4) $ file <filename>
Should give you the encoding of that text file.
For ex:
sf@orca:~$ echo $LC_ALL
en_US.UTF-8
sf@orca:~$ cat /tmp/xx
abcdefé
sf@orca:~$ file /tmp/xx
/tmp/xx: UTF-8 Unicode text

Hello All,
I am not able to understand how the encoding is handled. I would be happy
if someone can tell what is happening in the following scenario:
1. I have created a database with EUC_KR encoding and created a table and
inserted some korean value into it.
=# CREATE DATABASE korean WITH ENCODING 'EUC_KR' LC_COLLATE='ko_KR.euckr'
LC_CTYPE='ko_KR.euckr' TEMPLATE=template0;
=# \c korean
korean=# SHOW client_encoding;
client_encoding
-----------------
UTF8
(1 row)
korean=# CREATE TABLE tbl (doc text);
korean=# INSERT INTO tbl VALUES ('그레스');
2. If I insert non-korean values it throws error:
korean=# INSERT INTO tbl VALUES ('データベース');
ERROR: character with byte sequence 0xe3 0x83 0xbc in encoding "UTF8" has
no equivalent in encoding "EUC_KR"
The error messages says all. PostgreSQL accepted 'データベース'
encoded in UTF-8 then tried to convert to EUC_KR but failed, because
EUC_KR does not accept languages other than Korean (and ASCII). What
else did you expect?
korean=# SELECT * FROM tbl;
doc
--------
그레스
(1 row)
3. I change the client encoding to EUC_KR and try inserting the same korean
characters and it throws an error:
korean=# SET client_encoding = 'EUC_KR';
SET
korean=# INSERT INTO tbl VALUES ('그레스');
ERROR: invalid byte sequence for encoding "EUC_KR": 0xa0 0x88
0xa0 is definitely not part of EUC_KR. That's why PostgreSQL throws an
error. I gues you are using UHC (Unified Hangul Code), rather than
EUC_KR. They are different encodings. You should do either:
1) Make sure that your termical encoding is EUC_KR.
2) set client_encoding = 'uhc';
Even the SELECT statement displays something different. I am not able to
understand why?
korean=# SELECT * FROM tbl;
doc
--------
����
(1 row)
This is because the same reason above.
Can someone please help me.
Thanks you,
Beena Emerson
