commit 678c462e213c3bf479bc93e4df5899ecfd914f91
Author: Pauli <paul.dale at oracle.com>

    Check for EOF in ASCII conversions.
    
    The C standard defines EOF as:
    
        ... an integer constant expression, with type int and a negative value...
    
    This means a conforming implemenetation could define this as a one of the
    printable characters.  This won't be a problem for ASCII.
    
    A specific test case has been added for EOF.
