Re: odbc problem on Japanese windows machine

Hi.

Sorry late reaction...
It is the conversion which is not supported by PostgreSQL. It does not have
the conversion definition between LATIN1 and SJIS.
See,

Subject: [ODBC] odbc problem on Japanese windows machine

Hi,

I am trying to use postgres odbc driver on windows Japanese machine, to test connection to a
remote postgres database. The database has latin1 encoding.

Connection tests to databases with latin1 encoding fail with this error message:

fatal: conversion between SJIS and LATIN1 is not supported

Connection tests to databases with utf8 encoding succeed.

I checked both server source and odbc driver source and saw that the message comes from
postgres server code.

It seems that the postgres odbc sends SJIS characters to the latin1 database and it cannot
convert.
I know that the next command retrieves with the same error:

alter database <db_name> set client_encoding="SJIS"

Is there any switch in the code to bypass local machine encoding?
Why does it send Japanese encoding?
Postgres odbc driver is not Japanese application. For what the conversion is needed?
Is there any way to overcome this problem?

Steps to reproduce error message:

1. Put postgres odbc drivers (psqlodbc30a.dll and psqlodbc35w.dll) under c:\windows\system32

2. Update machine registry with next values:
[HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers]
"PostgreSQL ANSI"="Installed"
"PostgreSQL Unicode"="Installed"

[HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\PostgreSQL ANSI]
"APILevel"="1"
"ConnectFunctions"="YYN"
"Driver"="c:\windows\system32\PSQLODBC30A.DLL"
"DriverODBCVer"="03.00"
"FileUsage"="0"
"Setup"=" c:\windows\system32\PSQLODBC30A.DLL"
"SQLLevel"="1"
"UsageCount"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\PostgreSQL Unicode]
"APILevel"="1"
"ConnectFunctions"="YYN"
"Driver"=" c:\windows\system32\PSQLODBC35W.DLL"
"DriverODBCVer"="03.51"
"FileUsage"="0"
"Setup"=" c:\windows\system32\PSQLODBC35W.DLL"
"SQLLevel"="1"
"UsageCount"=dword:00000001

3. Create datasource and test connection to latin1 encoding database:
Settings -> administrative tools -> data source (ODBC)
And then add system data source with postgres driver. Configure this data source to
connect to latin1 postgres database.
