This is a first step for adding QT_NO_INTEGRAL_STRINGS in the next commit. Mark setUtf16(const ushort *) as obsolete. Use the weak overload workaround, so that the call isn't ambiguous if it's called on a nullptr. [ChangeLog][QtCore][QString] Added setUtf16(const char16_t *) and setUnicode(const char16_t *) overloads. Task-number: QTBUG-125871 Change-Id: I25d12c19876466c235c0d9928aae6fd332836bf5 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> (cherry picked from commit be3bf632e1cf80b16475f8353e4753b38317626b) Reviewed-by: Qt Cherry-pick Bot <cherrypick_bot@qt-project.org>
