Devanagari ( Indian ) fonts are not being rendered by browsers

Question

I've developed java swing application for newspaper shop. When I make bill order by running my project from Netbeans, the bill is saved as an HTML file on given directory and devanagari fonts are rendered properly. eg.

But when I deploy my swing application as an EXE Installer file and tried same thing then I found that Devanagari characters are replaced by question mark.

eg.

In short, Everything is rendered properly by browsers when I try to make bill by running project in Netbeans. After deploying same project as an EXE application, bill font is not rendered properly by browsers.

The code to write Data from JTable to Html File is as follow.

CallableStatement cstmt;
    PreparedStatement pstmt;
    static DBConnect db;
    Object[][] rowdata;
    static String[] columnheads;
    static DefaultTableModel dtm;
    static ResultSet rs;
    static ResultSetMetaData rsmt;
    String curName,shop,address,owner,contact,sign,data,destPath;
    static int rows,columns,number;
    float total, discount;
    static TableRowSorter<DefaultTableModel> sorter;
    Vector curRow;
    ActionListener menuListener;
    Writer out;
    BufferedWriter bw;
    File file;
    JFileChooser chooser;

void printBill()
    {
        // bPrev.setValues(tBno.getText(), tDate.getText(), tCustomer.getText(), tTotal.getText(), tTotal2.getText(), tPrevBal.getText());

       try
       {
           rs=db.stmt.executeQuery("select value from SETTINGS where property='shop'");
           rs.next();
           shop=rs.getString(1);

           rs=db.stmt.executeQuery("select value from SETTINGS where property='address'");
           rs.next();
           address=rs.getString(1);

           rs=db.stmt.executeQuery("select value from SETTINGS where property='owner'");
           rs.next();
           owner=rs.getString(1);

           rs=db.stmt.executeQuery("select value from SETTINGS where property='contact'");
           rs.next();
           contact=rs.getString(1);

           rs=db.stmt.executeQuery("select value from SETTINGS where property='sign'");
           rs.next();
           sign=rs.getString(1);

           rs=db.stmt.executeQuery("select value from SETTINGS where property='savePath'");
           rs.next();
           destPath=rs.getString(1);

           dtm = (DefaultTableModel) BillTbl.getModel();
           file=new File(destPath+"Bill-"+tBno.getText()+".html");

           out=new FileWriter(file);
           bw=new BufferedWriter(out);

           bw.write("<header><title> Bill-No "+tBno.getText()+"</title></head><body><p align=center> <b> "+shop+" </b><br> <b> पत्ता : </b> "+address+" <br> <b> मालक : </b> "+owner+" <br> <b> भ्रमणध्वनी क्र. </b> "+contact+" <br>--------------------------------------------</br> <b> बिलक्रमांक : </b> "+tBno.getText()+"  &nbsp &nbsp &nbsp &nbsp <b> दिनांक : </b> "+new SimpleDateFormat("dd-MM-YYYY").format(new java.util.Date())+" <br> <b> ग्राहकाचे नाव : </b> "+tCustomer.getText()+" &nbsp &nbsp</p>");

           bw.write("<center><table border=1><tr>");
           for (int i=0;i<dtm.getColumnCount();i++)
           {
               if(i==0 || i==2 || i==4)
               {
                   bw.write("<th> &nbsp "+dtm.getColumnName(i)+" &nbsp </th>");
               }     
           }
           bw.write("</tr>");

           for (int i=0;i<dtm.getRowCount();i++)
           {
             bw.write("<tr>");
             for (int j=0;j<dtm.getColumnCount();j++)
             {
                if(j==0)
                {
                    bw.write("<td> &nbsp "+dtm.getValueAt(i,j).toString()+" &nbsp </td>");
                }
                else if(j==2 || j==4)
                {
                    bw.write("<td align=center>"+dtm.getValueAt(i,j).toString()+"</td>");
                }
             }
             bw.write("</tr>");
          }
          bw.write("</table><br><table border=0><tr><td rowspan=3><img src='"+sign+"' height=40 width=70></td><td align=right> रक्कम रू.

          bw.close();

          Desktop.getDesktop().open(file);
       }
       catch(Exception ex)
       {
           ex.printStackTrace();
       }
    }

You have to make changes for character set in html/jsp page also. You can find more details in google — Sambit, May 12 '19 at 19:24
Everything works fine when I make bill by running software on netbeans. But after deploying same application, if I try to make order ( bill ) then browsers shows ???? instead of characters. — अक्षय परूळेकर, May 12 '19 at 19:24
Post the smallest stripped down version of the HTML file that demonstrates the font problem. Delete most of the content before posting here. — Basil Bourque, May 12 '19 at 19:59
"Clean and Build" options makes jar file of project in 'projectDirectory/dist'. Then I use Excelsior Jet named software to convert this jar file to EXE installer. — अक्षय परूळेकर, May 13 '19 at 03:55
When I run application in Netbeans, content is written to html file dynamically with devanagari font as expected. But when I run same application without netbeans, it writes question marks ( ??? ) instead of Devanagari letters in html file. — अक्षय परूळेकर, May 13 '19 at 03:58
I half suspect that this _also_ doesn't work in the HTML version on computers that don't have devanagari fonts installed. It feels very much like you're relying on fonts being available without every putting in the code that _ensures_ the font is used. So, create a new dir, and then create a [mcve]: do you tell Java which font asset to use, and do you make sure it gets (LEGALLY!) bundled with your executable? — Mike 'Pomax' Kamermans, May 13 '19 at 04:27
“…when I deploy my swing application as an EXE Installer file…” On the same computer, or on a different computer? — VGR, May 13 '19 at 05:39
