Issues with character encodings fixed

There has been a persistent issue with our servers ever since we moved to a new server layout and app server. Several characters were handled incorrectly, and translated into question marks.

This problem should now finally be fixed, and special characters should show up correctly.

Feel free to test here and report in case you run into problems!
