I think it's the same as the quoted site.
However, In programming, there are times when you want to operate on
bytes, code points, or grapheme clusters.
UTF-8 can't solve everything, what to program is important for
programmers (byte programming, character programming etc).
Also, other character encodings are also important in mainly CJK.
Character set has a lot of consider of many things.
