backup + restore fails

I have installed the new postgresql-8.1.msi on windows XP.
All standard as proposed except: encoding UTF8 and locale Germany/german as
a service. (UTF8 seams to be important, the locale not?)

Using pgAdmin-III I have connected and created a new database. Optionally I
can create a table - same result. Analyse: no errors found.

Then: backup compressed and restore using pgAdminIII.
I will get the error: pg_restore: [archiver (db)] could not execute query:
ERROR: invalid byte sequence for encoding "UTF8": 0xe46973
Command was: --
Why that???

In the backup or in the SQL-dump (see below) the are special german
"Umlaute" ("ä")

This is only comment and I have no influence on it, but possibly the source
of the problem?

If I hit "ok" expecting to close the window the same happens again. I have
clipped the result here:

When I delete the table before restoring I get this:

The table "test" is very simple: Only 1 field as primary key!

My active command level codepage: 850, in windows 1252.
