# Multibytes encodings, such as UTF-16 and UTF-32, pose a problem
# when transferring data between different computer systems, either
# by copying a file directly or using network communication. Different
# systems use different ordering of the high- and low-order bytes.
# This characteristic of the data, known as its endianness, depends
# on factors such as the hardware architecture and choices made by
