To avoid encoding a byte order mark (BOM), use an "le" or "be" suffix, e.g.
>>> 'Hello!'.encode('utf-16le')
b'H\x00e\x00l\x00l\x00o\x00!\x00'
Sometimes a data format includes the byte order, which makes using a
BOM redundant. For example, strings in the Windows registry use
UTF-16LE, without a BOM.
