tdf#137639 qt: UTF-16-encode mime data for "text/plain;charset=utf-16"
Return a `QVariant` from a `QByteArray` containing the UTF-16-encoded
characters when mime data for mime type "text/plain;charset=utf-16"
is requested in `QtMimeData::retrieveData`, rather than
a `QVariant` created from a a `QString`, to ensure that UTF-16
encoded data is actually used in the end.
While `QString` uses UTF-16 encoding itself,
`QMimeDataPrivate::retrieveTypedData` from the Qt library
would convert the retrieved `QString` data to UTF-8 [1],
resulting in a mismatch because UTF-8 encoded data would
actually be returned when UTF-16-encoded one has
been requested.
This gets called as follows:
0 QtMimeData::retrieveData
1 QMimeDataPrivate::retrieveTypedData
2 QMimeData::data
3 QtMimeData::deepCopy
