I think "standard repertoire based on Unicode" may be confusing the issue.

As I understand it, you're saying something like

    For strings, repr will delegate to display_string.

    Users can (and should) supply a display_string function
appropriate to their own system.

    The default display_string will display ASCII, and unicode-escape
everything else.



Except that you're leaving wiggle room for refinements like:

    "OK, we'll display all of Latin-1 by default, because we did in the past"
or
    "For security reasons, the control character codes will always be
escaped, instead of passing them to string_display"
