[docs] [issue21071] struct.Struct.format is bytes, but should be str

STINNER Victor added the comment:

Is it safe to assume PyUnicode_AsUTF8() is null-terminated?

Yes, Python ensures that the string is null terminated.

(like PyBytes_AS_STRING() is)

Yes, PyBytes_AS_STRING() also ends with a null byte. By the way, Unicode strings internally ends with a null character. ---------- _______________________________________ Python tracker http://bugs.python.org/issue21071 _______________________________________
