private static void UpdateFontSettings(WordprocessingDocument content, WordprocessingDocument template)

    {
        if (content != null && content.MainDocumentPart != null && content.MainDocumentPart.FontTablePart != null &&
            template != null && template.MainDocumentPart != null && template.MainDocumentPart.FontTablePart != null)

            IEnumerable<OpenXmlPart> partsToDelete = from idPartPair in content.MainDocumentPart.FontTablePart.Parts
                                                     select idPartPair.OpenXmlPart;

            content.MainDocumentPart.FontTablePart.DeleteParts(partsToDelete);

            StreamReader streamReader = null;

我建议您在创建StreamWriter时设置编码类型。我相信大多数系统默认为ANSI，但您可能需要UTF8或其他东西。
