Thank you for the response.
Sorry, I had not indicated OS information.
OS information is the following:
Red Hat Enterprise Linux Server release 6.2 Kernel 2.6.32-220.el6.x86_64 on an x86_64

The reason which was being verified using the LANG environment variable, I thought that the value of a LANG environment variable was set as LC_CTYPE when the LC_CTYPE environment variable and the LC_ALL environment variable are not set up.

The LC_CTYPE environment variable was set up and re-verified.
The result of psql command is following.

[Result]
% setenv LC_CTYPE ja_JP.eucJP

% psql postgres -f test.txt -o result.txt EUC_JP

% psql postgres -f test.txt > result.txt
UTF8

% psql postgres -o result.txt < test.txt
UTF8

% psql postgres < test.txt > result.txt
UTF8

Even when a LC_CTYPE environment variable was set up, the result did not change.
What do you think?
