Downgrade SQL2005 To SQL2k - Unicode ANSI Issue

Hello,

I created a script with database publishing wizard to convert a SS2005
db into a SS2k db. The script has schema and data and looks very good.
When I try to start the created script in SS2k-Query analyzer, I get an
error like (in german)

Server: Nachr.-Nr. 105, Schweregrad 15, Status 1, Zeile 2
Öffnendes Anführungszeichen vor der Zeichenfolge '�퉊䘒
'.
It meens - translated from german- 'opening quote before string
<blabla>'

In the sript it stops at this line:
EXEC dbo.sp_addextendedproperty @name=N'GUID', @value=N'�퉊䘒

In the script many lines before I have many other GUIDs which QA
doesn't complain, so it's an Unicode/ANSI-issue I guess. What to do
now?

thanks
