What steps will reproduce the problem?
1. Open character palette with Qt 4.8.0 or 4.8.1.
2. Select non-BMP characters (U+10000 or higher)

What is the expected output?
See the attached Mozc_character_palette_qt4.7.4.png

What do you see instead?
See the attached Mozc_character_palette_qt4.8.1.png

Anyway we are planning to add a workaround against this issue in the next
