Currently I have a problem with some German characters like ö,ä,ü and so on in my web part. SharePoint didn’t show these characters correctly. It just shows some crazy stuff like ö.
The Element.xml use <?xml version="1.0" encoding="utf-8"?>.
The Sharepoint header uses <meta http-equiv="Content-Type" content="text/html; charset=utf-8">.
If I add a special character in the text field in SharePoint, the characters will show correctly. How could I fix this?
