this can only be explained by the query behind the OracleCommand.
the "invalid character" usually arises when you have data type mismatches or inconsistencies in the query/procedure

And if nothing works out, try putting Try Catch Block and handle the exception to see what error message is comming up.

Seemed to work, but i dont get any information in my Datagridview

is this the correct way of getting the information from the SQL query to the datagridview?

Me.Dgvstatistikk.DataSource = dataleser

I havent worked on datagridview much, but there are just two possiblities, either there are no values return by your query or either databinding ith datagridview is wrong.
