Do you mean in C++ or in rustc? In rustc, they are represented as Unicode
Scalar Values which are 4 bytes wide.
From the docs over here: [https://doc.rust-lang.org/std/primitive.char.html]
So I'm assuming they could be represented as `int32_t`s which would also
make sense for the check
Cheers,
Arthur
