I've got a map where I integrate spatial point data from an ArcGIS Server. Now I want a popup triggered via a click on the point. I know how everything works and the popup is displayed.
But I've got the problem that some of the source's columns names are using German special characters (ü,ä,ö).
That leads to a strange behaviour when displaying the popup; instead of the data it shows the column's name. So how could I change the code's column tag to get the right information?
The code is published under this JSFiddle.
Any help is welcome.
