Is there a off-by-one bug with the end of the second string? Or am I really
misunderstanding Apple’s counting strategy? The second string seems to be only
9 characters long. And shouldn't index 18 point to the first character of the
third string instead? (Well, the 18 is right assuming the length of 10 is
actually right. But it isn’t, so it’s not.)
2. Since the first half of my data is in a table view, I guess I’ll supply a
list of ranges for the cells’ text and flag that matches shouldn’t straddle
boundaries. But should my text for the second half (i.e. the text view) be
included in that list (going Make-Range(first-half-length,
second-half-length))? Or as a separate string for the text view’s find bar
(going Make-Range(0, second-half-length))?
