Consider glitchr for an extreme case of what is meant by combining characters: https://twitter.com/glitchr_

Whether it needs to be unbounded is a different discussion: Programmers tend to avoid constants that aren't 0, 1, or a power of two. "Unbounded" is easier than guessing (e.g. UCS16) wrong.

0,1,infinite is a nice rule, but it certainly complicates a spec. I just cannot comprehend something being unbounded when we are talking about characters we use to communicate. Given the number of possibilities of 64-bits or 128-bits, I'm having a bit of a tough time thinking that their isn't a bound on what we can type into the computer.
