Actually, they don't. Instead, they refer to "coded character sets",
in W3C terminology: mapping of characters to natural numbers. See

http://unicode.org/faq/basic_q.html#14

The term "UCS-2" is a character set that can encode only encode 65536
characters; it thus refers to Unicode 1.1. According to the Unicode
Consortium's FAQ, the term UCS-2 should be avoided these days.

No, we shouldn't. The term UCS-2 is deprecated, see above.
