I'm trying to pass a string value to a Python function and get a utf-8 string value. The function retrieves Japanese characters and returns characters in another language.
I used ctypes.windll.user32.MessageBoxW in the Python script and made sure there is no problem with the Python function. And I tried a simple function like return 'hello world' to test. I also checked every function with assert. I guess the problem starts with PyBytes_AsString. It always returns DB DB DB DB DB DB DB... (in hex). But I don't know how to fix this.
char* result;
PyObject* module, *func, *arg, *ret, *value;
Py_Initialize();
PyObject* sysPath = PySys_GetObject("path");
PyObject* path = PyUnicode_FromString(".");
PyList_Append(sysPath, path);
module = PyImport_ImportModule("test");
if (module != 0)
{
const wchar_t* w = L"翻訳テスト";
func = PyObject_GetAttrString(module, "translate");
arg = PyTuple_New(1);
value = PyUnicode_FromWideChar(w, wcslen(w));
PyTuple_SetItem(arg, 0, value);
ret = PyObject_CallObject(func, arg);
PyObject* repr = PyObject_Repr(ret);
PyObject* str = PyUnicode_AsEncodedString(repr, "utf-8", "strict");
result = PyBytes_AsString(str);
Py_DECREF(repr);
Py_DECREF(str);
Py_DECREF(module);
Py_DECREF(func);
Py_DECREF(arg);
Py_DECREF(ret);
fstream file("text.txt", std::ios::out);
file << result;
file.close();
}
Py_Finalize();
