Java ASCII file output

[jmace]

When I try to output an ASCII value to a file, it sometimes writes the wrong value. Example:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.PrintWriter;

public class test {
	public static void main(String args[]){
		                          //Supposed to:
		writeFile("./test.txt"); //write ASCII 147
		readFile("./test.txt"); //read ASCII 147
	}
	
	public static boolean writeFile(String path){
		try{
			PrintWriter fo = new PrintWriter(new FileOutputStream(new File(path)));
			fo.print((char) 147); //WRITES "?" TO FILE (ASCII 63, NOT 147)
			fo.close();
		}catch(Exception e){
			return true;
		}
		return false;
	}
	
	public static boolean readFile(String path){
		try {
			BufferedReader fi = new BufferedReader(new FileReader(path));
			char c[] = fi.readLine().toCharArray();
			System.out.println((int) c[0]); //OBVIOUSLY PRINTS 63 INSTEAD OF 147
			fi.close();
			return true;
		} catch (Exception e){
			e.printStackTrace();
			return false;
		}
	}
}

What am I doing wrong? Any help would be great.
