(sz uint32)

// is responsible for writing 'sz' more valid UTF-8
// bytes to the stream.
func (mw *Writer) WriteStringHeader(sz uint32) error {
	switch {
	case sz <= 31:
		return mw.push(wfixstr(uint8(sz)))
	case sz <= math.MaxUint8:
		return mw.prefix8(mstr8, uint8(sz))
	case sz <= math.MaxUint16:
		return mw.prefix16(mstr16, uint16(sz))
	default:
		return mw.prefix32(mstr32, sz)
	}
