Thai language Configuration in Oracle
I have an issue regarding configuring Thai language in oracle (PL/SQL Developer). I have configured Thai language 'AMERICAN_AMERICA.TH8TISASCII' in regedit. Also I configured Environment variables in my computer. But still when I connect PL/SQL developer and retrieve data, columns that should show Thai descriptions are showing garbage data. Please help me.
Example of garbage data is '¿¿¿¿¿¿¿¿'
Oracle Configurations is as below :
regedit->computer->HKEY_LOCAL_MACHINE->SOFTWARE->ORACLE->KEY_OraDB11g_home1
Windown Configuration is as below:
Mycomputer->Advanced system setting->Advanced System Settings->Environment Variables -> (here i added variable)
the same configuration is done by my peers and they got the configuration but i am not able to do this

I have configured Thai language 'AMERICAN_AMERICA.TH8TISASCII' in regedit.
It means you have configured your NLS_LANGUAGE as AMERICAN and NLS_TERRITORY as AMERICA. Which is wrong.
You should select the following:
NLS_LANGAUGE=THAI
NLS_TERRITORY=THAILAND
You need to do this at:
- Database level - init.ora file
- Environment level - NLS LANG settings
I think your characterset is fine.
UPDATE OP got the issue with PL/SQL Developer tool.
You can enter "alter session" commands in the AfterConnect.sql file in the PL/SQL Developer installation directory. For example:
alter session set nls_date_format='dd-mm-yyyy'; alter session set nls_territory='THAILAND'; alter session set nls_language='THAI';
