After I posted this, I read Guido's earlier message that the
case may not be as clear. So please take this as my own opinion,
not as a given - some people apparently want repr to provide
unambiguous output also.

If so, I still don't think the security mechanisms of Unicode
apply - if you have combining characters in the string, and
the precombined version also exists in Unicode, then those
algorithms may still not help. Likewise for compatibility
characters.
