I try to implement a text entry from JEditorPane . When reading text using the .getText() method and then writing to the txt file, the Cyrillic alphabet is converted into characters like "в" . How can this be overcome?

    But you can get a fragment of the code for receiving text and writing - Artem Konovalov
  • Sorry, I still do not understand how to add the code. Added to the text of the question. - Artik

    Apparently the encoding is not the same, but which one do you choose when opening a file? - Artem Konovalov
  • There the meaning is this: there is an html file, I open it and read the text. This text is processed and transmitted to JEditorPane ("text / html", text). At this stage, everything is OK. Next, this text must be saved in a txt file. This is where the shoals climbs. The file itself is ANSI-encoded. Tried to change, does not help. I tried to put CP1251 and UTF8 encoding when reading a file. Does not help. - Artik

It is difficult to say what exactly the problem is, I put a quick code on it. The file should be saved in utf-8.

 public class Solution extends JFrame { private Solution() { super("title"); JEditorPane pane = new JEditorPane(); pane.setEditable(true); pane.setContentType("text/html"); pane.setText("<h2>hello world</h2>"); getContentPane().add(new JScrollPane(pane), "Center"); JPanel panel = new JPanel(); panel.setLayout(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); c.gridwidth = 1; c.gridheight = 1; c.anchor = GridBagConstraints.EAST; c.fill = GridBagConstraints.NONE; c.weightx = 0.0; c.weighty = 0.0; getContentPane().add(panel, "South"); panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); JButton saveButton = new JButton("Save"); saveButton.addActionListener(e -> { String text = pane.getText(); JFileChooser fc = new JFileChooser(); System.out.println(text); if (fc.showSaveDialog(null) == JFileChooser.APPROVE_OPTION) { try (BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fc.getSelectedFile()), StandardCharsets.UTF_8))) { bw.write(text); } catch (Exception saveEx) { JOptionPane.showMessageDialog(null, saveEx.getMessage(), "Ошибка!", JOptionPane.ERROR_MESSAGE); } } }); panel.add(Box.createVerticalStrut(10)); panel.add(saveButton); panel.add(Box.createVerticalGlue()); panel.setBorder(BorderFactory.createEmptyBorder(2, 4, 2, 4)); getContentPane().add(panel, "East"); } public static void main(String[] args) { JFrame f = new Solution(); f.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent evt) { System.exit(0); } }); f.setSize(500, 400); f.setVisible(true); }}
  • I tried to add StandardCharsets.UTF_8. Did not help. I specifically added the line System.out.println (text); for control. Crackers are also displayed in the console. That is, the problem begins already when reading text from the JEditorPane (in the String line text = pane.getText ();) - Artik
  • @Artik and in what encoding html file? Is it in jeditpane normally displayed? - Artem Konovalov
  • That's the thing, in JEditPane it is displayed normally. ANSI file. And when reading text from JEditPane, it produces & # ... characters. - Artik
  • @Artik is a problem in HTMLWriter in the output() method, all characters whose code exceeds 127 converts to & # symbol_code. To avoid this, either redefine it or change text/html to text - Artem Konovalov
  • The whole thing is that I need the html markup. I want to use it to create templates for printing, which will be substituted data values. - Artik

Try this design

 String text = new String(previewPane.getText().getBytes("UTF-8"));

PS Conducted an experiment screen from my computer Please give me the full code of your application.

  • I also tried it. Does not help. - Artik
  • So stop, how do you read the file? - plesser
  • I added the full text to the question. True, I did not understand how beautifully insert the text of the code. - Artik
