[issue9198] Should repr() print unicode characters outside the BMP?

[Ezio Melotti]

Ezio Melotti <ezio.melotti at gmail.com> added the comment:

I suggest to:
  1) keep the current behavior for non-BMP chars (i.e. print them normally);
  2) change isprintable to consider the Zx categories printable (this will affect repr() too);
  3) change displayhook (*NOT* sys.stdout.encoding) to use backslashreplace when the string contains chars that are not encodable with sys.stdout.encoding *.

* note that this will affect only the objects that are converted with repr() in the interpreter e.g. ">>> x = 'foo'; x" and *NOT* ">>> x = 'foo'; print(x)". Since the first behavior exists *only* in the interactive interpreter it won't be inconsistent with normal programs ("x = 'foo'; x" in a program doesn't display anything).
