> Although the current NumPy converter code tries to detect endian against a given object, it does not work for a built-in object. This is because a build-in object may have {{native |}} byte order.
> This issue causes test failure as follows:
> {code:java}
> FAILED pyarrow/tests/test_array.py::test_array_from_numpy_unicode - UnicodeDecodeError: 'utf-32-le' codec can't decode bytes in position 0-3: code point not in range(0x110000)
> FAILED pyarrow/tests/test_array.py::test_array_from_strided - UnicodeDecodeError: 'utf-32-le' codec can't decode bytes in position 0-3: code point not in range(0x110000)
> FAILED pyarrow/tests/test_array.py::test_array_from_numpy_str_utf8 - UnicodeDecodeError: 'utf-32-le' codec can't decode bytes in position 0-3: code point not in range(0x110000) {code}
