FPUTU8(3)

NAME
fputu8 - utf-8 library function manual page

SYNOPSIS
#include <utf-8.h>
int
fputu8(unsigned int c, FILE *output);
int
utf8fputc(unsigned int c, FILE *output);
int
utf8putc(unsigned int c, FILE *output);
int
utf8putchar(unsigned int c);

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).
