I am trying to print malayalam words fetched from rssfeeds provided by various medias like "Matrubhumi" "Indiavision" to a jtext area.
What I am doing is saving all the topics from rssfeed to a text file and then reading them line by line to print it into a textarea. But at some words I am getting ArrayIndexOutofBoundException.
For example printing "ബോസ്റ്റണ് സംഭവം: അമേരിക്കയിലെ സിഖ് സമൂഹം ആശങ്കയില് " gives the error. Please point out any mistakes I am making. Also I have changed font to "Meera" so I do not think it is the problem. Also strings like " ബംഗാളില് ചിട്ടി കമ്പനി പൊളിഞ്ഞു, സംഘര്ഷം " do not show any error and opens the application window. Thanks in advance.
BufferedReader demo = new BufferedReader(new FileReader(Name));
jScrollPane1 = new javax.swing.JScrollPane();
jTextArea1 = new javax.swing.JTextArea();
setBackground(java.awt.Color.white);
setPreferredSize(new java.awt.Dimension(1366, 768));
jTextArea1.setColumns(30);
jTextArea1.setRows(10);
jTextArea1.setBorder(null);
jTextArea1.setFont(new java.awt.Font("Meera", 1, 24));
jTextArea1.setEditable(false);
jScrollPane1.setViewportView(jTextArea1);
jTextArea1.setWrapStyleWord(true);
jTextArea1.setLineWrap(true);
while ((sCurrentLine = demo.readLine()) != null){
jTextArea1.append(sCurrentLine);
}
private javax.swing.JTextArea jTextArea1;
public static final java.lang.Character.UnicodeBlock MALAYALAM = null;
The rest of the code is auto generated code from netbeans.
This is the second class. The main class deals with fetching rssfeed and saving the topics into a text file. And the name of the text file is passed to this class where FileReader() is used to gain access to the file and fetch the contents line by line to a string variable "sCurrentLine". And using jTextArea.append() append the text into the text area.

Also I tried to run the program by enclosing the error generatingportion in a try catch, but then i got another ArrayIndexOutofBoundException but this time at a diffrent line.Code Segment
String RSSName;
RSSName = "Matrubhumi";
