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
```go
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
Input: [239 187 191 104 101 108 108 111]
ReadAll with BOM skipping [104 101 108 108 111]
Detected encoding: UTF8
ReadAll with BOM detection and skipping [104 101 108 108 111]
Input: [104 101 108 108 111]
ReadAll with BOM skipping [104 101 108 108 111]
Detected encoding: Unknown
ReadAll with BOM detection and skipping [104 101 108 108 111]
