This is an article you should really read.

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

Next, to answer your question:

  • To Read a file encoded with UTF-8, use a BufferedReader:

    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8"));

  • To Write a file encoded with UTF-8 use a BufferedWriter:

    BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file), "UTF-8"));

Make sure that the transmittion of the data through the sockets goes correct.

ASCII-7 is compatible with UTF-8. There is nothing you need to do turn turn ASCII-7 into UTF-8 (but it doesn't work the other way)
