This is not possible, since utf16 strings have (like utf8) a variable 
character length, and QString's internals do not support this.

You can cast your string to const QChar* and use it as argument of 
QConstString ( const QChar * unicode, uint length ), provided that:
- you are sure that all characters in your utf16 string have only 16 bits (you 
may need to check that)
- you did not compile Qt with QT_QSTRING_UCS_4. In other words, QChar has 2 
bytes and not 4. You can check that at compile time, a sizeof(QChar) should 
be enough
