utfbom 
The package utfbom implements the detection of the BOM (Unicode Byte Order Mark) and removing as necessary. It can also return the encoding detected by the BOM.
Installation
go get -u github.com/dimchansky/utfbom
Example
package main
import (
"bytes"
"fmt"
"io/ioutil"
"github.com/dimchansky/utfbom"
)
func main() {
trySkip([]byte("\xEF\xBB\xBFhello"))
trySkip([]byte("hello"))
}
func trySkip(byteData []byte) {
fmt.Println("Input:", byteData)
// just skip BOM
output, err := ioutil.ReadAll(utfbom.SkipOnly(bytes.NewReader(byteData)))
if err != nil {
fmt.Println(err)
return
}
fmt.Println("ReadAll with BOM skipping", output)
// skip BOM and detect encoding
sr, enc := utfbom.Skip(bytes.NewReader(byteData))
fmt.Printf("Detected encoding: %s\n", enc)
output, err = ioutil.ReadAll(sr)
if err != nil {
fmt.Println(err)
return
}
fmt.Println("ReadAll with BOM detection and skipping", output)
fmt.Println()
}
Output:
$ go run main.go
