OpenXML将单词保存为txt，编码为UTF8

Question

我想将doc文件转换为txt文件，但有些字符丢失，请参阅以下代码：

    object format = WdSaveFormat.wdFormatText;

    doc.SaveAs(ref outputFilePath, ref format,
      ref ObjectConstants.False, ref Unknown,
      ref Unknown, ref Unknown,
      ref Unknown, ref Unknown,
      ref Unknown, ref Unknown,
      ref Unknown, ref Unknown,
      ref Unknown, ref Unknown,
      ref Unknown, ref Unknown);

我的问题是如何将txt的编码设置为UTF8？
