c# - XmlWorker ParseToElementList UTF-8 特殊字符丢失

Question

我已经修改了 XMLWorkerHelper.ParseToElementList 方法，以便我使用 UTF-8 编码来转换附加的 HTML。

编码设置为 UTF-8。

//ParseToElementList overided method (UTF-8)
public static ElementList ParseToElementList(String html, String css)
{
    // CSS
    ICSSResolver cssResolver = new StyleAttrCSSResolver();
    if (css != null)
    {
        ICssFile cssFile = XMLWorkerHelper.GetCSS(new MemoryStream(Encoding.UTF8.GetBytes(css)));
        cssResolver.AddCss(cssFile);
    }

    // HTML
    CssAppliers cssAppliers = new CssAppliersImpl(FontFactory.FontImp);
    HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
    htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
    htmlContext.AutoBookmark(false);

    // Pipelines
    ElementList elements = new ElementList();
    ElementHandlerPipeline end = new ElementHandlerPipeline(elements, null);
    HtmlPipeline htmlPipeline = new HtmlPipeline(htmlContext, end);
    CssResolverPipeline cssPipeline = new CssResolverPipeline(cssResolver, htmlPipeline);

    // XML Worker
    XMLWorker worker = new XMLWorker(cssPipeline, true);
    XMLParser p = new XMLParser(worker);
    p.Parse(new MemoryStream(Encoding.UTF8.GetBytes(html)));

    return elements;
}

将解析后的 HTML 填充到 PdfCell 中

List<IElement> elementsIzv = ParseToElementList(nonConformity[Helper_ND_Display.porociloIzvedba].ToString(), null);
foreach (IElement e in elementsIzv)
{
    porociloData.AddElement(e);
}
resitevTable.AddCell(porociloData);

除了字符 č(Č) (č) 之外的所有工作都没有被转换（丢失）。我错过了什么或者 ParseToElementList 方法中是否存在错误？使用 GetInstance 方法转换 HTML

XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, reader);

正在根据需要转换所有字符。
