The problem is in _pysqlite_build_py_params function at connection.c. In case
we have text we do the following code:
case SQLITE_TEXT:
val_str = (const char*)sqlite3_value_text(cur_value);
cur_py_value = PyUnicode_FromString(val_str);
/* TODO: have a way to show errors here */
if (!cur_py_value) {
PyErr_Clear();
Py_INCREF(Py_None);
cur_py_value = Py_None;
}
break;
As you can see we call PyUnicode_FromString instead of text_factory.
I started making a patch to fix this by passing the text_factory to
_pysqlite_build_py_params function but I currently have a problem with setting
the result to the sqlite. User text_factory may return any type of object and I
can't see how to handle that...
