utfbom
![Coverage Status](https://coveralls.io/repos/github/dimchansky/utfbom/badge.svg?branch=master)
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))
var encStr string
switch enc {
case utfbom.UTF8:
encStr = "UTF8"
case utfbom.UTF16BigEndian:
encStr = "UTF16 big endian"
case utfbom.UTF16LittleEndian:
encStr = "UTF16 little endian"
case utfbom.UTF32BigEndian:
encStr = "UTF32 big endian"
case utfbom.UTF32LittleEndian:
encStr = "UTF32 little endian"
default:
encStr = "Unknown, no byte-order mark found"
}
fmt.Println("Detected encoding:", encStr)
output, err = ioutil.ReadAll(sr)
if err != nil {
fmt.Println(err)
return
}
fmt.Println("ReadAll with BOM detection and skipping", output)
fmt.Println()
}
