Add support for Unicode surrogate characters and planes above zero.HEADmaster

If the selected font supports the required characters, the text will be displayed correctly.
If the selected font does not support such characters, empty boxes will be displayed in place of the expected text.

Part of the code changes comes from Qt4 code.
