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.

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

STANDARDS

     ISO 10646-1: 1993 (``Unicode''), RFC 2279: 1998 (``UTF-8''), ISO

DIAGNOSTICS

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