Odkmeta: “column header type not found”

Hi @Jonas, and welcome to the ODK forum! When you have a chance, I'd encourage you to introduce yourself here. Doing so helps build community!

survey.csv contains a group whose name is group_ smis (with a space). However, spaces aren't allowed in field names. Have you been able to use this XLSForm successfully?

The name of that group seems to be the cause of this error message. However, I also see non-ASCII characters in the CSV files. For example, the label of field note2 contains the text "Centre National de SpÇcialisation sur le maãs (CNS-Maãs)", but Ç and ã are not ASCII characters.

Hope that helps!
