#1083 bug with special characters

[max]

I stumbled about this bug with special characters in Pd: If you type special characters in Pd it will overwrite what is already written instead of insert.
To test it on a comment do this:
1. make a new comment: "this is a comment"
2. place the cursor somewhere in the middle
3. add a character. It will insert, making the comment longer.
4. now try a special character like an umlaut. It will overwrite the letters already there instead.
