SQLCL danish characters not showing

Hi i'm trying to use sqlcl instead of plus80w.exe in an forms12c form.

sqlcl is installed on windows 10 client machines and the used language is Danish.

I've build a form that loads an sql query from a table column into at file, that I write to the client pc( C:\Users\username\scriptfile.sql).

I then use webutil.client_host to excute sqlcl with the C:\Users\username\scriptfile.sql file I wrote to the client, on the client pc.

webutil.client_host executes the statement

CMD /c start C:\Oracle\product\sqlcl\bin\sql user/userpwd@dbname @C:\Users\username\scriptfile.sql
