Although Unicode characters are supported in the standard library, they are actually less used.Byte.gopackage mainimport"fmt"func main() { varbyte for b =0;b177;b++{ fmt.Printf("%d %c\n",b,b) }}Rune.gopackage mainimport"fmt"func main() { // byte => uint8 // rune => int32 "golang你好" fmt.Println(len(s)) 0 forrange s {
