Read and Write Text in ANSI format

Question

Please have a look at the following code

import java.io.*;  public class CSVConverter  {     private File csvFile;     private BufferedReader reader;     private StringBuffer strBuffer;     private BufferedWriter writer;     int startNumber = 0;     private String strString[];      public CSVConverter(String location, int startNumber)     {         csvFile = new File(location);         strBuffer = new StringBuffer("");         this.startNumber = startNumber;           //Read         try         {          reader = new BufferedReader(new FileReader(csvFile));          String line = "";           while((line=reader.readLine())!=null)          {              String[] array = line.split(",");               String inputQuery = "insertQuery["+startNumber+"] = \"insert into WordList_Table ('Engl','Port','EnglishH','PortugueseH','Numbe','NumberOf','NumberOfTime','NumberOfTimesPor')values('"+array[0]+"','"+array[2]+"','"+array[1]+"','"+array[3]+"',0,0,0,0)\"";               strBuffer.append(inputQuery+";"+"\r\n");              startNumber++;           }         }         catch(Exception e)         {             e.printStackTrace();         }         System.out.println(strBuffer.toString());          //Write         try         {             File file = new File("C:/Users/list.txt");             FileWriter filewrite = new FileWriter(file);              if(!file.exists())             {                 file.createNewFile();             }               writer = new BufferedWriter(filewrite);               writer.write(strBuffer.toString());             writer.flush();             writer.close();          }         catch(Exception e)         {             e.printStackTrace();         }      }      public static void main(String[]args)     {         new CSVConverter("C:/Users/list.csv",90);     } } 

I am trying to read a CSV file, edit the text in code, and write it back to a .txt file. My issue is, I have Portuguese words, so the file should be read and write using ANSI format. Right now some Portuguese words are replaced with symbols in the output file.

How can I read and write text data into a file in ANSI format in Java?

To read a text file with a specific encoding you can use a FileInputStream in conjunction with a InputStreamReader. The right Java encoding for Windows ANSI is Cp1252.

reader = new BufferedReader(new InputStreamReader(new FileInputStream(csvFile), "Cp1252")); 

To write a text file with a specific character encoding you can use a FileOutputStream together with a OutputStreamWriter.

writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file), "Cp1252")); 

The classes InputStreamReader and OutputStreamWriter translate between byte oriented streams and text with a specific character encoding.
