Hi,

I answered to a similiar problem on the [GENERAL] list a few days ago. In
short: You can use "recode" in a pipe between dump and restore like
"pg_dump database|recode ascii..utf8|psql newdatabase" to get rid of unicode
problems while transferring from a different encoding. Please look at my
statements on the[GENERAL] list for the gory details.

Regards, Frank.
