How to display surrogate pair character with QPainter::DrawText()

[useryy]

In the following way, an UCS2 character can be displayed correctly. But when it comes surrogate pair, nothing displayed. I know that two QChar inside a QString will be used for a surrogate pair. The question is how to let the system know it's a surrogate pair not two QChars and display it correctly?

uint a = 0x20000 //surrogate pair character 
QString str;
str.append(a);
painter.Drawtext(str);

Well, not with String::append(uint) -- that will most likely translate to String::append(QChar(uint)), which will truncate away the high-order part of your literal.
