Nope.

A new string consists of a record that contains the encoding ID, element 
size, reference count, length and the pointger to the content:

   TAnsiRec = Packed Record
     CodePage    : TSystemCodePage;
     ElementSize : Word;
{$ifdef CPU64}
     { align fields  }
     Dummy       : DWord;
{$endif CPU64}
     Ref         : SizeInt;
     Len         : SizeInt;
     First       : AnsiChar;
   end;

So each string variable has it's own dedicated encoding ID and can't 
point to that of another string.
