What you need to figure out is what encoding the text you are typing is in. You're telling psql it's EUC_KR but it evidently isn't. If you're typing these characters manually then it's probably determined by a setting of the terminal-emulator program you're using. But if you're copying-and-pasting then things get more complicated.
Also, what you did above is not what Amit suggested: he wanted you to put the variable assignments on the same command line as the psql invocation, so that they'd affect the environment passed to psql. I'm suspicious of his solution because I'd have thought the terminal program would set up the right environment ... but you might as well try it.
I tried with both the assignment and invocation in same line. Again it gave the same result.
Maybe the problem is with copy paste. I will look into it.
