Why doesn't 'a' or 'b' get printed?

I came across this in Golang and the result is not so obvious to me, here is the code:

package main

import "fmt"

func main() {
    a := 'a'
    b := a | 'b'
    fmt.Println(b)
}

Does it print a? Does it print b?

No, the result in the console is 99, why?

    Look, ain ASCII code it is 97and bin ASCII it is 98.

    By doing the ORyou are doing the ORof 97and 98in binary, that is,

    1100001 OR 1100010 = 1100011, that is 99.

    Edit: If you print the result by formatting it, instead of showing the ascii code we see that it shows the c(ascii value 99)

    package main

import "fmt"

func main() {
    a := 'a'
    b := a | 'b'
    fmt.Printf("%+q", b)
}

    *I have changed the println to printf and I have formatted it
