Long live qUtf16Printable()
QString::asprintf() has the ability to take a ushort* array as
obtained from QString::utf16() and insert that into the output
with an %ls conversion.
But no-one ever used this, because just passing QString::utf16()
to QString::asprintf() creates a warning about wchar_t* expected,
but ushort* provided.
The new qUtf16Printable() macro adds the necessary casts (via void*
to prevent any "type-punned pointer" warnings) to make
passing QString::utf16() to QString::asprintf() work silently.
This should greatly reduce the need to do a round-trip via utf-8
just to print the contents of a QString.
[ChangeLog][QtCore] Added qUtf16Printable().
