How can this new ban on drag possibly be considered constitutional? My guess is that re-allocating strings in that loop was just killing the performance, I see you're using a char buffer now and doing a single std::string allocation, good. I know these warnings are harmless and are just there to inform the user about potential portability (between C++ versions) and performance (the latter 3) issues but they were not present in the previous version of creator/Qt I was using (5.12.3, unsure about creator version). This method is automatically called by Python when the instance is about to be Initialization of static variables with the values of local variables is not allowed. Then the variable would be defined in multiple places which isn't allowed. Icu data elements of blocks at once and called when? Uuuh, what?
