DESCRIPTION

     The fputu8() function of utf-8 library converts a UTC-4 (31-bit Unicode)
     integer to one or more bytes representing its UTF-8 value, and writes the
     result to a file.

     utf8fputc() and utf8putc() are macros which simply give fputu8() a name
     that may be more convenient to remember. They are defined in <utf-8.h>.

     The fputu8() function and the macros take two arguments: c, the UTC-4
     code, and input, which can be any open file.

     The utf8putchar() macro sends output to stdout.


RETURN VALUES

     fputu8() returns 0 on success; EOF if output is NULL or cannot be written
     to; 1 if c is not a valid UTC-4 code (i.e., its high bit is set).
