International characters in MonetDB

Hello All, I have been trying to do some bulk uploads from CSV files into a MonetDB database.  All the fields in the database are VARCHAR.  The text in some of the fields contains international characters such as : ü, Ó, é  etc. When I execute :  copy into database from 'filename.csv' using delimiters ',','\n','"' NULL as ''; I get an error stating that the fields with words containing the international characters could not be imported, and the import process stops. How can I solve this issue? (I am running Monetdb on windows) Thanks, SG
