Comment (by sergiomdgomes):

 More broadly, and as food for thought, I'm not entirely sure why we're
 hardcoding arrays of hexadecimal literals, which then need to be
 transformed into a string for the tests. It seems to me that it would make
 more sense to directly include the desired code sequences as JS string
 literals and call it a day.

 Perhaps we're afraid of a contributor coming along with an editor that
 messes it up, by e.g. rewriting them to an equivalent sequence? Or perhaps
 this comes from a time when we couldn't rely on browsers supporting
 unicode characters in string literals?

 I don't think we necessarily need to change this, and I think the current
 patch works well as a forward-looking and robust solution, it just struck
 me as odd.
