As people keep telling you, this is a nonsense question. UTF-8 does not have sourcecode. UTF-8 is a function from streams of octets to streams of codepoints and vice versa. It is specified very simply, and there are many reference implementations (including the one posted here). There are no codepages in Unicode. (Or I suppose there is exactly one.) There have been a couple of specification changes in the history of UTF-8; the last one was in 2003. So it's unlikely you ever need to consider previous versions, in which certain now forbidden codepoints are allowed to appear.
