copy command PANIC in --encoding='utf8' createdb option

I installed PostgreSQL-8.0beta4 on Linux Fedora Core2.

and first I made database test1. and create table t1, copy data from
file 'test.dmp'
$ createdb test1
CREATE DATABASE

$psql test1
test1=> create table t1 (col1 varchar(100));
CREATE TABLE
test1=> show client_encoding;
client_encoding
-----------------
EUC_KR
(1 row)

and load data from 'test.dmp' file
test1=> \copy t1 (col1) from '/tmp/test.dmp'
\.
ERROR: invalid byte sequence for encoding "EUC_KR": 0xb85f
CONTEXT: COPY t1, line 1, column col1: "/system/workbin/등락종??.TXT.20040319"
test1=>

the test.dmp file is
$ cat test.dmp
/system/workbin/등락종??.TXT.20040319
$ od -h test.dmp
0000000 732f 7379 6574 2f6d 6f77 6b72 6962 2f6e
0000020 eeb5 f4b6 bec1 5fb8 5fbc 542e 5458 322e
0000040 3030 3034 3133 0a39
0000050

the first cast is good..
but second case, creatdb with --encoding='utf8'

$ createdb test1 --encoding='utf8'
CREATE DATABASE

$ psql test1
test1=> show client_encoding;
client_encoding
-----------------
UNICODE
(1 row)
test1=> set client_encoding = 'uhc';
SET
test1=> \copy t1 (col1) from '/opt/lgsec/dmp/test.dmp'
\.
