[Idle-dev] Unicode within IDLE

[Neil Hodgson]

   I was pleased to find that IDLE is already using a Unicode based text
widget so is able to display non-roman strings.

   However, the syntax colouring is disturbed by this. It appears to be
confused by the difference in length when measuring bytes or characters.

  If:
s="?"#H
  is the first line of the file with ? replaced by a two byte UTF-8
character, the string highlight colour extends over the '#' and the
colouring of the rest of the file is out by one.
