ascii encoding error in block input (COPY INTO)

Hi, I found previous noteshttps://www.monetdb.org/pipermail/users-list/2010-November/004529.htmlhere that the server would expect UTF-8 input from the client or COPY INTO, so I need to work on my my Western ISO Latin 1 files. However, the error message is confusing about, COPY INTO complains about "'ascii' codec can't decode byte 0xc4 in position 8: ordinal not in range(128)."

Shall I convert the data to UTF-8 then, or is that futile? What has the ascii codec to do with UTF-8?

Thanks,

Laszlo
