[BQN treats characters as an affine space](https://mlochbaum.github.io/BQN/doc/types.html#characters) which is basically a fancy name for each character being an integer (indicating the code point) and a Boolean (indicating the "characterness": 1 for character, 0 for non-character). Arithmetic on characters applies to both the code point and the characterness. Here, we take the minimum which gives the desired code point, and since both arguments are characters, the characterness stays at 1.
