 O^/Ọ

[Try it online!][TIO-kcpxbl20]

Takes input as a list of the two strings, e.g. `['abcde', '01234']`.

### How?

```
O # ord: cast to number (automatically vectorizes)
 ^/ # Reduce by XOR. XOR automatically vectorizes
 and pads as desired to work if the two strings are different lengths
 Ọ # chr: cast to character (vectorizes once again)
```
