golang GBK与UTF-8互转的例子

package main

import (
    "code.google.com/p/mahonia"
    "fmt"
)

func main() {
    //"你好，世界！"的GBK编码
    testBytes := []byte{0xC4, 0xE3, 0xBA, 0xC3, 0xA3, 0xAC, 0xCA, 0xC0, 0xBD, 0xE7, 0xA3, 0xA1}
    var testStr string
    utfStr := "你好，世界！"
    var dec mahonia.Decoder
    var enc mahonia.Encoder

    testStr = string(testBytes)

    dec = mahonia.NewDecoder("gbk")
    if ret, ok := dec.ConvertStringOK(testStr); ok {
        fmt.Println("GBK to UTF-8: ", ret, " bytes:", testBytes)
    }

    enc = mahonia.NewEncoder("gbk")
    if ret, ok := enc.ConvertStringOK(utfStr); ok {
        fmt.Println("UTF-8 to GBK: ", ret, " bytes: ", []byte(ret))
    }
    return
