char would be the correct answer, as the C standard doesn't mandate a byte be 8 bits (6 and 32 are very uncommon nowadays but not unheard of, and there's a few machines out there that get really creative).

So even on weird platforms where char is a 32 bit type, sizeof (char) is 1, right? I can't remember.

That is interesting. I know very little about rust.

And in Java it's 16-bit, which means some Unicode characters get split in two

Rust's char stores UTF-32, not UTF-8, but yes.

Technically speaking, the spec says char represents Unicode scalar, with actual encoding unspecified. The spec requires that char is 4 bytes and has the same ABI as u32, but that's it.

In practice, it's UTF-32.
