Trying out some more settings of multibyte endcoding, I could not find any combination of settings solving the problem described. The only solution working up to now was to give the following statement within the tcl application: "encoding system identity" This makes the insert of national special characters work as expected. But is that a clean solution (I don't know what identity exactly does)? If yes, where to insert this statement in the pgaccess interface (inserting it in "main.tcl" helps only partly) ?
