Encode file in UTF-8 and use java encoding aware streams operators:
new InputStreamReader(new FileInputStream(file), "UTF-8")

An other "frequent" encoding would be Windows Latin-1, "Windows-1252" – Joop Eggen Dec 14 '12 at 09:28

i am using the code FileReader fr= new FileReader(new File("path of the file")); BufferedReader br= new BufferedReader(fr); then where to pass the encoding standard. – Adesh singh Dec 14 '12 at 09:35

@user1868052 read javadoc http://docs.oracle.com/javase/1.4.2/docs/api/java/io/FileReader.html use InputStreamReader instead of FileReader – Aleksander Gralak Dec 14 '12 at 09:40

You need to find out the exact encoding that the file uses, and then specify that in the
InputStreamReaderparameter.
Nevertheless it is often best to reader character data by wrapping your InputStream with an InputStreamReader into Reader or BufferedReader
BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(your file), "UTF-8"));
Edit For Comment:
FileReader uses Java's platform default encoding, which depends on the system settings of the computer on which its running on.
Unfortunately
FileReaderdoes not allow to set encoding. Instead, you have to use Above code to get the desire encoding for your file.

You are right. But this is a little offtopic. The question is about encoding not efficiency. – Aleksander Gralak Dec 14 '12 at 09:32

i have checked the files are using UTF8 encoding standard but its not reading the special characters – Adesh singh Dec 14 '12 at 09:56
