I stop quoting here because I already collected enough instances of <'s> for
making my point...

It seems to me that a word such as "lambda's" is just an English plural noun
(also spelled "lambdas"), so it should be allowed in identifiers, it should
count as a unit for word selections, etc.

Clearly, U+0027 (APOSTROPHE, general category "Po" = other punctuation) is
not fit for this purpose, because it has the wrong category and because it
is ambiguously used as a quotation mark.

But neither U+2019 (RIGHT SINGLE *QUOTATION* MARK, general category "Pf" =
final *punctuation*) seems fit for the purpose.

So, why does the Unicode book suggest U+2019 as the preferred character for
apostrophe? Wouldn't U+02BC (MODIFIER LETTER APOSTROPHE, general category
"Lm" = modifier letter) be a better choice?
