Question

我需要知道为什么这段代码不能编译，go编译器一直告诉我使用invalid-utf编码，但我不明白这究竟发生了什么。我收到的错误。

$ go build Example#2.go
command-line-arguments
.\Example#2.go:32:15: invalid UTF-8 encoding

对此的任何帮助都将非常感激。我知道它是一个简单的程序，但它是为了向我的编程语言类演示语言，这只是一个简单的例子，展示了方法名称必须如何链接到结构以及接口如何工作。就像我说的那样，它适用于go playground但不适用于实际的编译器。

package main

import (
    "fmt"
)

type Person struct {
    Name    string
    Address Address
}

type Address struct {
    Number string
    Street string
    City   string
    State  string
    Zip    string
}
    type Citizen struct {
    Country string
    Person
}
type speak interface {
    Talk()
}

func (p *Person) Talk() {
    fmt.Println("Hi, my name is", p.Name)
}

func (p *Person) Location() {
    fmt.Printf("I’m at %v %v %v %v %v\n", p.Address.Number, 
    p.Address.Street, p.Address.City, p.Address.State, p.Address.Zip)
}

func (c *Citizen) Nationality() {
    fmt.Println(c.Name, "is a citizen of", c.Country)
}
func (c *Citizen) Talk() {
    fmt.Println("this is the citizen talk method")
}
func Converse(s speak) {
    s.Talk()
}

func main() {
    p := Person{
        Name: "Jim",
        Address: Address{
            Number: "1",
            Street: "College Avenue",
            City:   "exampleland",
            State:  "StateLand",
            Zip:    "8675309",
        },
    }
    c := Citizen{}
    c.Name = "John"
    c.Country = "Somewhereland"
    c.Person.Address.Number = "1337"

    c.Person.Address.Street = "Haxor Lane"
    c.Person.Address.City = "Lazy"
    c.Person.Address.State = "Foo"
    c.Person.Address.Zip = "192.168.1.1"

    p.Talk()
    p.Location()

    ///////////////
    fmt.Println("")
    ///////////////

    c.Person.Talk()
    c.Talk()
    ///////////////
    fmt.Println("")
    ///////////////
    c.Nationality()
    c.Location()
    ///////////////
    fmt.Println("")
    Converse(&p)
    Converse(&c)
}

原来这是由“I'm”//＆gt;＆gt;中的撇号引起的。 fmt.Printf（“我在％v％v％v％v％v \ n”，p.Address.Number，p.Address.Street，p.Address.City，p.Address.State，p.Address的.zip）

为什么不使用go 1.10编译器编译，但将在goplayground上运行
