Need help with the Pointers in C

I have a special character called ô. When it is declared as a character variable its showing it can be printed. But when it is declared as a character pointer variable its showing it cannot be printed. I am just wondering why its happening like this..

c1 = '@';
c2 = 'ô';
char *fp;
fp="XXô";

if ( isprint(c1) )
printf ("%c can be printed \n ", c1);
else
printf ("%c cannot be printed \n ", c1);
if ( isprint(c2) )
printf ("%c can be printed \n ", c2);
else
printf ("%c cannot be printed \n ", c2);

while (*fp){

if ( isprint(*fp)) )
{
printf ("%s can be printed \n ", fp);
fp++;
}
else
{
printf ("%s cannot be printed \n ", fp);
fp++;
}
}


This is my sample code...If I remove the pointer declaration and print the character alone its showing it can be printed. If I include the pointer declaration and try to print it from the pointer its showing it cannot be printed.,..please advise on this..

NAME
explain_printf_or_die - formatted output conversion and report errors SYNOPSIS
#include <libexplain/printf.h> int explain_printf_or_die(const char *format); int explain_printf_on_error(const char *format); DESCRIPTION
The explain_printf_or_die function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_printf_on_error function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, but still returns to the caller. format The format, exactly as to be passed to the printf(3) system call. RETURN VALUE
The explain_printf_or_die function only returns on success, see printf(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_printf_on_error function always returns the value return by the wrapped printf(3) system call. EXAMPLE
The explain_printf_or_die function is intended to be used in a fashion similar to the following example: int result = explain_printf_or_die(format); SEE ALSO
printf(3) formatted output conversion explain_printf(3) explain printf(3) errors exit(2) terminate the calling process COPYRIGHT
