SYNOPSIS


.Fd #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.
