I want to know the answer to the following question:
what is another name for a low-surrogate code point?
All the background I'm provided with is that "A high-surrogate code point (also known as a leading surrogate) followed by a low-surrogate code point (also known as a trailing surrogate) together form a surrogate pair used in UTF-16 to represent 1,048,576 code points outside BMP.". Is that enough to answer the question?
