(UCS1, UCS2, UCS4).
Benchmark:
+-------------------------------------+---------+----------------------+
| Benchmark | ref | change2 |
+=====================================+=========+======================+
| repr('abc') | 100 ns | 103 ns: 1.02x slower |
+-------------------------------------+---------+----------------------+
| repr('a' * 100) | 369 ns | 369 ns: 1.00x slower |
+-------------------------------------+---------+----------------------+
| repr(('a' + squote) * 100) | 1.21 us | 946 ns: 1.27x faster |
+-------------------------------------+---------+----------------------+
| repr(('a' + nl) * 100) | 1.23 us | 907 ns: 1.36x faster |
+-------------------------------------+---------+----------------------+
| repr(dquote + ('a' + squote) * 100) | 1.08 us | 858 ns: 1.25x faster |
+-------------------------------------+---------+----------------------+
| Geometric mean | (ref) | 1.16x faster |
