speaks psql unicode?

Hi,

if i try to import data via SQL-Inserts (exported with pgManager) out
from an utf-8 file i get always parse errors in the first line.

After switching to ascii and using of SET client_encoding TO 'latin1'
i can import all lines, but some unicode-characters are, like
expected, damaged.

Now my question: Can psql process Unicodefiles?

Thanks for any tipp,
thomas
