FGETU8(3)

NAME
fgetu8 - utf-8 library function manual page

SYNOPSIS
#include <utf-8.h>
unsigned int
fgetu8(FILE *input);
unsigned int
utf8fgetc(FILE *input);
unsigned int
utf8getc(FILE *input);
unsigned int
utf8getchar();

DESCRIPTION
The fgetu8() function of utf-8 library reads one or more bytes from a UTF-8 formatted text file, and converts them to single UTC-4 (Unicode) value.

utf8fgetc() and utfgetc() are macros which simply give fgetu8() a name that may be more convenient to remember. They are defined in <utf-8.h>.

The fgetu8() function and the macros take one argument: input, which can be any open file.

The utf8getchar() macro reads input from stdin.

RETURN VALUES
If input is NULL, or if a premature end-of-file condition occurs, fgetu8() returns EOF. If input contains valid UTF-8 codes, fgetu8() returns the converted UTC-4 value. Otherwise, it returns UTF8INVALID, defined in <utf-8.h>.

DIAGNOSTICS
You should always check the RETURN VALUES against EOF and UTF8INVALID.
