Not possible to use special characters as column ID/name in formulas #45
Description
There is an error message when using a column ID that contains a special character (like Swedish wowels å, ä, ö) in the formula tab. See attached screenshot. The workaround is to use a instead of å, ä and o instead of o (but silly).
In the attached screenshot i try and use a column ID containing an "ä", in the word "magnetfält", and receive the error upon pressing "apply" in the formula tab.
