I have heard conflicting opinions from people - according to Wikipedia, see here.
They are the same thing, aren't they? Can someone clarify?

1. Unicode
There're lots of characters around the world,like "$,&,h,a,t,?,张,1,=,+...".
Then there comes an organization who's dedicated to these characters,
They made a standard called "Unicode".
The standard is like follows:
PS:Of course there's another organization called ISO maintaining another standard --"ISO 10646",nearly the same.
2. UTF-8
As above,U+0024 is just a position,so we can't save "U+0024" in computer for the character "$".
There must be an encoding method.
Then there come encoding methods,such as UTF-8,UTF-16,UTF-32,UCS-2....
Under UTF-8,the code point "U+0024" is encoded into 00100100.
00100100 is the value we save in computer for "$".
