Reverse Unicode code points

Return text with its Unicode code points in reverse order. A surrogate pair representing one supplementary character must stay intact. Combining marks are separate code points; this is not grapheme-aware reversal.

Examples

Constraints

0–10,000 code points; input contains well-formed Unicode (no lone surrogates). No normalization.

A little nudge

Reveal one hint at a time. Give yourself a moment to try it.

Worked solution

Try your own approach first, then compare the reasoning.
