(Go) Convert a File's Character Encoding from UTF-8 to UFT-8-BOM

To add a utf-8 BOM to a file is just a matter of prepending these 3 bytes to the file: 0xEF 0xBB 0xBF.

This may be difficult in some programming languages, or it may be trivial in either. Therefore, the Chilkat solution you see here might be helpful, or in a language such as C++, the Chilkat solution isn't really necessary because it's easy to do yourself.

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    charset := chilkat.NewCharset()

    charset.SetFromCharset("utf-8")
    charset.SetToCharset("bom-utf-8")

    success := charset.ConvertFile("qa_data/txt/helloWorld.txt","qa_output/helloWorldBom.txt")
    if success != true {
        fmt.Println(charset.LastErrorText())
        charset.DisposeCharset()
        return
    }

    fmt.Println("Success.")

    charset.DisposeCharset()
