FoofyFox Unicode Transformation Format (ffutf)

This small library of functions provides a Unicode-aware interface for the C programming language. These functions can be categorised into two types:

• File manipulation functions that read or write to regular files using file pointers.
• Unicode-aware string length functions that check the length of Unicode strings.

Usage

This file can be included with current code as follows:

C

#include "ffutf.h"

C++

extern "C" {
    #include "ffutf.h"
}

In addition, if the macro FFUTF_FAILSAFELY is specified at compile time with -DFFUTF_FAILSAFELY, safer alternatives to invalid input will be considered. If a value such as -DFFUTF_FAILSAFELY=foo is specified, the value that the macro expands to will be ignored.

For the type field, to specify an endianness, please use the bitwise OR operator. For example, to specify a UTF-16 encoding with a little endian format, use UTF16 | LE.
