以前(正如在较早的答案中提到的),完成此操作的"简单"方法包括使用需要CGO的第三方包并包装iconv库.出于许多原因,这是不受欢迎的.值得庆幸的是,在相当长的一段时间里,只使用围棋作者提供的包(不是在主包集中,而是在Go Sub-Repositories个包中)就有了一种更好的All Go方式来做到这一点.
golang.org/x/text/encoding
包为通用字符编码定义了一个接口,该接口可以与UTF-8相互转换.golang.org/x/text/encoding/simplifiedchinese
子包提供GB18030、GBK和HZ-GB2312编码实现.
下面是读写GBK编码文件的示例.请注意,当数据被读/写时,第io.Reader
和第io.Writer
在飞翔上进行编码.
package main
import (
"bufio"
"fmt"
"log"
"os"
"golang.org/x/text/encoding/simplifiedchinese"
"golang.org/x/text/transform"
)
// Encoding to use. Since this implements the encoding.Encoding
// interface from golang.org/x/text/encoding you can trivially
// change this out for any of the other implemented encoders,
// e.g. `traditionalchinese.Big5`, `charmap.Windows1252`,
// `korean.EUCKR`, etc.
var enc = simplifiedchinese.GBK
func main() {
const filename = "example_GBK_file"
exampleWriteGBK(filename)
exampleReadGBK(filename)
}
func exampleReadGBK(filename string) {
// Read UTF-8 from a GBK encoded file.
f, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
r := transform.NewReader(f, enc.NewDecoder())
// Read converted UTF-8 from `r` as needed.
// As an example we'll read line-by-line showing what was read:
sc := bufio.NewScanner(r)
for sc.Scan() {
fmt.Printf("Read line: %s\n", sc.Bytes())
}
if err = sc.Err(); err != nil {
log.Fatal(err)
}
if err = f.Close(); err != nil {
log.Fatal(err)
}
}
func exampleWriteGBK(filename string) {
// Write UTF-8 to a GBK encoded file.
f, err := os.Create(filename)
if err != nil {
log.Fatal(err)
}
w := transform.NewWriter(f, enc.NewEncoder())
// Write UTF-8 to `w` as desired.
// As an example we'll write some text from the Wikipedia
// GBK page that includes Chinese.
_, err = fmt.Fprintln(w,
`In 1995, China National Information Technology Standardization
Technical Committee set down the Chinese Internal Code Specification

slight extension of Codepage 936. The newly added 95 characters were not
found in GB 13000.1-1993, and were provisionally assigned Unicode PUA
code points.`)
