I have a question regarding my ModalDialog.
There is an option called title:
options.title = 'Benutzer wählen';
Now if I display the dialog:
var dlg = SP.UI.ModalDialog.showModalDialog(options);
The ä from "wählen" doesn't get accepted by SharePoint, I also tried using:
But that didn't change anything. It was just standing there as plain text.
