  "github.com/signintech/gopdf"
  "github.com/signintech/gopdf/fonts"
)

func main() {

  pdf := gopdf.GoPdf{}
  pdf.Start(gopdf.Config{Unit: "pt", PageSize: gopdf.Rect{W: 595.28, H: 841.89}}) //A4
  pdf.AddFont("THSarabunPSK",new(fonts.THSarabun),"THSarabun.z")
  pdf.AddFont("Loma",new(fonts.Loma),"Loma.z")
  pdf.AddPage()
  pdf.SetFont("THSarabunPSK","B",14)
  pdf.Cell(nil,   ToCp874("Hello world  = สวัสดี โลก in thai"))
  pdf.WritePdf("x.pdf")
  fmt.Println("Done...")
}

func ToCp874(str string) string{
  str, _ = iconv.ConvertString( str, "utf-8", "cp874")
