Example
Convert string
package main
import (
"fmt"
"github.com/qiniu/iconv"
)
func main() {
cd, err := iconv.Open("gbk", "utf-8") // convert utf-8 to gbk
if err != nil {
fmt.Println("iconv.Open failed!")
return
}
defer cd.Close()
gbk := cd.ConvString("你好，世界！")
fmt.Println(gbk)
}Output to io.Writer
package main
import (
"fmt"
"github.com/qiniu/iconv"
)
func main() {
cd, err := iconv.Open("gbk", "utf-8") // convert utf-8 to gbk
if err != nil {
fmt.Println("iconv.Open failed!")
return
}
defer cd.Close()
output := ... // eg. output := os.Stdout || ouput, err := os.Create(file)
autoSync := false // buffered or not
bufSize := 0 // default if zero
w := iconv.NewWriter(cd, output, bufSize, autoSync)
fmt.Fprintln(w, "你好，世界！")
w.Sync() // if autoSync = false, you need call Sync() by yourself
}Input from io.Reader
package main
import (

}
defer cd.Close()
