New Post: Loading ä ü ß ö etc.

Hi,

I using the ScintillaNET Editor for a simple IDE to learn more and more about C#.
Now there's one problem. When i load a file into the ScintillaNET Editor, the letters ä ü ß and all other additional characters are replaced with a rectangle like that �.

How can I fix them?
I found out when i edit the file and save it (with my editor) and load it again the additional characters are there and aren't replaced!
