JEditorPane中渲染数学符号的问题

我正在尝试在JEditor中呈现以下代码，这在Chrome和Mozile浏览器中工作正常但在EditorPane中没有。

<html><body>In the given figure, ABCD is a quadrilateral 
in which BD = 10 cm, AL <SPAN>^</SPAN> BD, 
CM <SPAN style=\"FONT-FAMILY:Symbol\">^</SPAN> 
BD such that AL = 4 cm and CM = 6 cm. 
Find the area of quadrilateral ABCD.<BR>
<IMG align=middle </body></html>

使用Unicode处理标签的工作正常，但我想使用标签显示它。

此代码可以解决您的问题。

                // make it read-only
            editorPane.setEditable(false);
            // add an html editor kit
            HTMLEditorKit htmlkit = new HTMLEditorKit();
            HTMLDocument htmlDoc = (HTMLDocument) htmlkit.createDefaultDocument();
            editorPane.setEditorKit(htmlkit);

            String htmlString = "<html><body>In the given figure, ABCD is a quadrilateral in which BD = 10 cm, AL <SPAN>^</SPAN> BD, CM <SPAN style=\\\"FONT-FAMILY:Symbol\\\">^</SPAN> BD such that AL = 4 cm and CM = 6 cm. Find the area of quadrilateral ABCD.<BR><IMG align=middle </body></html>";
            Reader htmlStringReader = new StringReader(htmlString);

            try {
                htmlkit.read(htmlStringReader, htmlDoc, 0);
            } catch (IOException e1) {
                // TODO Auto-generated catch block
                System.out.println(e1.getMessage());
                e1.printStackTrace();
            } catch (BadLocationException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
            editorPane.setEditorKit(htmlkit);
            htmlDoc.putProperty("ZOOM_FACTOR", new Double(0.5));
            editorPane.setDocument(htmlDoc);
