#ifndef NVIM_ICONV_H
#define NVIM_ICONV_H
// iconv can be linked at compile-time as well as loaded at runtime. In the
// latter case, some function pointers need to be initialized after loading
// the library (see `iconv_enabled()` in mbyte.c). These function pointers
// are stored in globals.h. Since globals.h includes iconv.h to get the
// definition of USE_ICONV, we can't include it from iconv.h. One way to
// solve this conundrum would be perhaps to let cmake decide the value of
// USE_ICONV, or to put the USE_ICONV definition in config.h.in directly. As
// it stands, globals.h needs to be included alongside iconv.h.
#ifdef HAVE_CONFIG_H
# include "auto/config.h"
#endif
// Use iconv() when it's available, either by linking to the library at
// compile time or by loading it at runtime.
#if (defined(HAVE_ICONV_H) && defined(HAVE_ICONV)) || defined(DYNAMIC_ICONV)
# define USE_ICONV
#endif
// If we don't have the actual iconv header files present but USE_ICONV was
// defined, we provide a type shim (pull in errno.h and define iconv_t).
// This enables us to still load and use iconv dynamically at runtime.
