在Go中使用UTF-8字节字符串将命令行输出转换为Unicode代码点

package main

import (
    "fmt"
    "os/exec"
)

func main() {
    cmd := exec.Command("echo", "你好")
    output, err := cmd.Output()
    if err != nil {
        fmt.Println("命令执行失败：", err)
        return
    }

    utf8Str := string(output)
    fmt.Println("UTF-8字节字符串：", utf8Str)
}

package main

import (
    "fmt"
    "os/exec"
    "unicode/utf8"
)

func main() {
    cmd := exec.Command("echo", "你好")
    output, err := cmd.Output()
    if err != nil {
        fmt.Println("命令执行失败：", err)
        return
    }

    utf8Str := string(output)
    fmt.Println("UTF-8字节字符串：", utf8Str)

    for len(utf8Str) > 0 {
        r, size := utf8.DecodeRuneInString(utf8Str)
        fmt.Printf("Unicode代码点：%U\n", r)
        utf8Str = utf8Str[size:]
    }
}
