Oracle Client_charset

I am using 19c client and my database's NLS parameters like these:

enter image description here

Also my clients specs are:

While (Windows 10 x64) I am using sqplus, I get this(you can see my NLS_LANG environment variable on the top of command line):

enter image description here

My 19c client home regedit NLS_LANG variable also is set to AMERICAN_AMERICA.W8ISO8859P9.

Yet, when I using TOAD for Oracle:

and using SQL Developer:

I got confused. On the internet they say NLS_LANG environment variable should be enough for setting client character set, but clearly it isn' t.

Due to this configuration difference, I am seeing "fıtıkçışahap"(on sqlplus) as "fıtıkçışahap"(on SQL Developer and TOAD for Oracle)

How can I overcome this situation?

Thanks in advance!

Solution

  • My PostgreSQL database' s encoding was tr_TR.UTF8, so still UTF8. It should have been LATIN that support Turkish character set. Changing it to tr_TR.iso8859 solved my problem.
