I am aware  but how is the receiving end meant to deal with them? Is  
it meant to keep the quotation marks around any quoted-string, even  
when that therefore results in non-exist things like a character set  
called "UTF-8" (with quotes)? Or does the behaviour need to be  
specific to each and every use of quoted-string need to have it  
defined separately?
