No, it shouldn't. The code in GtkEditable currently assumes that 
the contents of your buffer are encoded according to the 
current locale. 

You can transfer UTF8 encoded text on the X clipboard - 
see:

 http://www.dcs.ed.ac.uk/home/jec/programs/xfsft/UTF8-selections.text

(Havoc's text widget has an example of handling both UTF8_STRING
 and old-style STRING). 

But gtkeditable does not currently handle this. In GTK+-1.4,
it will.
