as you see, some special character did changed the lines although i intended NOT to change them.

as far as i know, Bufferedwriter / Reader should work in unicode by default.

    Well BufferedWriter and BufferedReader are encoding agnostic – they never deal with the actual encodings, as they’re just buffering existing readers and writers.

    Now FileWriter and FileReader use the default system encoding (urgh). To work round this, you should usually use an InputStream / InputStreamReader or OutputStream / OutputStreamWriter pair (possibly wrapped in a BufferedReader / BufferedWriter), and specify the encoding explicitly.

    You haven’t said what you’re actually reading from – is it a file? Do you know the encoding of the file?
