> I would like to update the `write_utf8` function but I would need to find a way to wrap `const char* data` as a PyBytes instance without making a memory copy to be able to pass it to my `_Pickle_write_large_bytes`. You should pass it as a memoryview instead: https://docs.python.org/3/c-api/memoryview.html#c.PyMemoryView_FromMemory
