For clarity (I know you know what a rune is but your description felt a little misleading imo):

A rune is just an alias for int32. But it's context usually means unicode chars which are indeed multi-byte.

You can still use byte arrays (or "slice" if you're writing idiomatic Go, but that's another tangent again) too though.

Also "byte" in Go is another alias, but for int8. But that shouldn't come as a surprise to anyone :)

Thank you for the clarification. Your explanation will be helpful to people. I wasn't planning on going into that technical detail, I was focused more on typical usage.
