ISO 15924 identifies scripts, not the characters used to write those
scripts.

I know you asked Michael, but:

Unicode does include information about which characters belong to which
scripts, but 0027, 02BC, and 2019 are all categorized as "Common." So no
help there.

Unicode also includes a General Category for each character. 0027 (the
straight ASCII apostrophe) is "Other Punctuation" and 2019 (the right
single quotation mark) is "Final Punctuation," while 02BC is "Modifier
Letter."

Unicode also has notes on these characters (prose) that specifically say
02BC is the right character to use as an orthographic letter, and 2019
is the right character to use as punctuation. Font limitations aren't
supposed to play into character identity decisions.

These languages do use the Latin script.
