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)

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.
