Getting Java to input strange characters from a file like c/c++ does it

Thanks for reading.

I'm taking a class where I need to read in PGM files character by character.
We're given code in C but I'd much rather use Java, so I tried rewriting it.
I'm hitting a snag though: using BufferedReader's read() method is returning
different values then what it should.

For example, where the c version...

int ci2;
FILE *fp2;

fp2=fopen("inputimage","rb");

ci2 = getc(fp2);

printf("%d", ci2);

returns "150" for some point in the file. The Java version...

int ci2;

BufferedReader ci2 = new BufferedReader(new FileReader("inputimage"));

ci2 = in2.read(t2);

System.out.print(ci2);

returns "8211".

If I convert the input from both the C and Java versions back to chars and output
to files, the C versions matches the original image exactly (which it should), but
the Java version is screwy.

I assume it has to do with Java VM converting the character encodings of the input,
but I have no clue as to how to get the correct input.

Here a simple example code that just reads in the pgm (without the header info) and
outputs it to another file character by character...

import java.io.*;

public class copy {
      public static void main (String[] args) throws IOException {

       int i,j, input;

       BufferedReader fin = new BufferedReader(new FileReader(args[0]));
       BufferedWriter fout = new BufferedWriter(new FileWriter(args[1]));

        // .pgm header info for a 256x256 image
       fout.write("P5\n256 256\n255\n");

        for (i=0; i<256; i++) {
            for (j=0;j<256;j++) {
                input = fin.read();
                fout.write(input);
            }
       }
       fin.close();
       fout.close();
    }
}

Thanks for any help anyone can provide.
