Yes, unicode() returns the UTF-16 code unit held inside the QChar
(which is just a 16 bit number...). If you want to UTF-16 encode code
points above 0xFFFF, you need surrogate pairs, i.e. pairs of QChars.
QChar itself offers methods such as isHighSurrogate/isLowSurrogate,
and various statics (surrogateToUcs4(QChar, QChar), isSurrogate(uint),
lowSurrogate(uint), etc.)

HTH,
