I want to know the answer to the following question:
How are two 16-bit units used?
All the background I'm provided with is that "UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units (4 × 8 bits) to handle each of the additional characters.". Is that enough to answer the question?
Answer: yes
