I know, I was counting on someone saying that it is needed and why.

With copying to clipboard, I found this in LCLQT in TQtClipboard.GetOwnerShip:

      if (QByteArray_length(Data) > 1) and QByteArray_endsWith(Data, #0) then
        QByteArray_chop(Data, 1);

With pasting from clipboard, there is this in LCL:


      if (ASize>0) and (pchar(MemStream.Memory)[ASize-1]=#0) then

If the #0 is specifically removed then maybe it doesn't need to be
added as well. As I see it, the stream (or array) size determines the
length, not the #0.

I can only test by installing lots of applications and testing if
copying/pasting still works after removing the #0.
