------ No one. You are confusing the knowledge of a coding scheme and the intrisinc information a "coding scheme" *may* have, in a mandatory way, to work properly. These are conceptualy two different things. I am convinced you are not conceptually understanding utf-8 very well. I wrote many times, "utf-8 does not produce bytes, but Unicode Encoding Units". A similar coding scheme: iso-6937 . Try to write an editor, a text widget, with with a coding scheme like the Flexible String Represenation. You will quickly notice, it is impossible (understand correctly). (You do not need a computer, just a sheet of paper and a pencil) Hint: what is the character at the caret position? jmf -- http://mail.python.org/mailman/listinfo/python-list
