Odd ... it Works For Me:

$ PGCLIENTENCODING=KOI8 psql regression
Welcome to psql 8.0.0beta4, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

regression=# \encoding
KOI8
regression=#

What locale settings are you using?
