For example the fact that some CJK characters should be displayed
differently depending on whether they're part of a C text, or a J text,
or a K text, so are they really "one and the same character"?

Of course, there are other related choices: which versions of β should
be one and the same and which shouldn't (e.g. I currently see in Unicode
a greek and a latin version plus some variants of a math version (tho
none in "roman" shape))?

There are murky areas, with no "one right answer", although Unicode has
had to choose somehow, i.e. doing the best it can with a messy situation.
