The functios like as PyUnicode_FromString use a printf format in char array argument. Example: PyUnicode_FromString("a%22b"); in module interprete the %22 as 22 blank spaces. A double quote in module add a backslash. Poc:
Y try send a string from c++ to python string using:
PyObject* pyString = PyUnicode_FromString("/abc/def.html/a%22.php?abc=&def=%22;%00s%01");
....
PyObject* pyArgs = Py_BuildValue("(z)", pyString);
...
PyObject_CallObject(pFunc, pyArgs);
But in script the string is bad:
function(data):
print(data)
The result is:
/abc/def.html/a bogus %pp?abc=&def= %;(null)%

PyUnicode_FromString() doesn't interpret %. Did you use PyUnicode_FromFormat()? |
