[docs] [issue18697] Unify arguments names in Unicode object C API documentation

Rune Tynan <runetynan@gmail.com> added the comment: I have some interest in making a fix for this. From discussion, I'm thinking that, barring names that already have clear meaning (EG, left/right for things with two parameters): - PyObject* that is unknown type remains `obj` - PyObject* with unicode string is `unicode` - const char*, const Py_UNICODE*, and const wchar* becomes `str` - const char, const Py_UNICODE, and const wchar become `ch` Those seem to be the intersect of most common and most descriptive names already seen. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue18697> _______________________________________
