Merlijn van Deen added the comment:
On the lowest level, this affects exec, eval(), compile() and input() (!). On a
higher level, more modules are affected:
modules ast, codeop, compiler, cProfile, dis, distutils (not sure), doctest,
idlelib, ihooks, pdb, pkgutil, plat-mac, py_compile, rexec, runpy and timeit
all call compile()
modules dbd, compiler, gettext, idlelib, lib2to3, lib-tk.turtle, logging,
mhlib, pdb, plat-irix5, plat-mac, rexec, rlcompleter and warnings all call
eval()
and modules Bastion, bdb, code, collections, cProfile, distutils, doctest,
idlelib, ihooks, imputil, pdb, plat-irix5, plat-irix6, plat-mac, profile,
rexec, site, timeit and trace all call exec.
Not all of them necessarily take user-supplied code - I haven't checked that.
After checking tests/test_pep263.py, it seems the behavior is a bit more
complicated than I initially thought: a str parameter is considered latin-1
unless either
a) an utf-8 bom is present, in which case it is considered utf-8
b) an # encoding: XXX line is present, in which case it is considered
to be in that encoding
In any case, I have attached a doc patch for exec, eval(), compile(), and
ast.literal_eval(), because I think these are the most widely used. I think
input() does not need a doc change because it explicitly refers to eval().
I ignored the subtleties noted above for the doc patch, simplifying to 'pass
either a Unicode or a latin-1 encoded string'.
