problems with writing binary file to .txt

[nscruggs]

so i have a problem writing this binary file "input.raw" to a text file "myFile.txt" my output just looks like this

ÁÂÃÂ

the "input.raw" file is supposebly 600000 bytes.

my code thus far looks like this, this is obviously written in C language and not C++ hope that is not a problem

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

void readFile();


int main ()
{

    readFile();


}

void(readFile())
{
  FILE * pFile;
  pFile = fopen("input.raw" , "rb");
  long lSize;
  unsigned char * buffer;
  size_t result;

  if (pFile==NULL)
  {
      fputs ("File error",stderr); exit (1);
  }

  // obtain file size:
  fseek (pFile , 0 , SEEK_END);
  lSize = ftell (pFile);
  rewind (pFile);

  // allocate memory to contain the whole file:
  buffer = (unsigned char*) malloc (sizeof(unsigned char)*lSize);
  if (buffer == NULL)
  {
      fputs ("Memory error",stderr); exit (2);
  }

  // copy the file into the buffer:
  result = fread (buffer,1,lSize,pFile);
  if (result != lSize)
  {
      fputs ("Reading error",stderr); exit (3);
  }

  /* the whole file is now loaded in the memory buffer. */
    FILE * pFile1;
    pFile1 = fopen ( "myfile.txt" , "wb" );
    fwrite (buffer , 1 , sizeof(buffer) , pFile1 );
    fclose (pFile1);

  // terminate
  fclose (pFile);
