The subject line is a bit misleading: the patch only touches
tp_print, not repr() output. And this is good, IMHO, since
otherwise eval(repr(string)) wouldn't necessarily result
Unicode objects don't implement a tp_print slot... perhaps
they should ?
About the ASCII proposal:
Would you be satisfied with what
currently implements ?
There are several places where an encoding comes into play with
the Unicode implementation. The above API currently changes
str(unicode), print unicode and the assumption made by the
implementation during coercion of strings to Unicode.
It does not change the encoding used to implement the "s"
or "t" parser markers and also doesn't change the way the
Unicode hash value is computed (these are currently still
hard-coded as UTF-8).
