/*
* iconv library using Win32 API to conversion.
*
* This file is placed in the public domain.
*
* Last Change: 2009-07-06
*
* ENVIRONMENT VARIABLE:
* WINICONV_LIBICONV_DLL
* If $WINICONV_LIBICONV_DLL is set, win_iconv uses the DLL. If
* loading the DLL or iconv_open() failed, falls back to internal
* conversion. If a few DLL are specified as comma separated list,
* the first loadable DLL is used. The DLL should have iconv_open(),
* iconv_close() and iconv(). Or libiconv_open(), libiconv_close()
* and libiconv().
* (only available when USE_LIBICONV_DLL is defined at compile time)
*
* Win32 API does not support strict encoding conversion for some
* codepage. And MLang function drop or replace invalid bytes and does
* not return useful error status as iconv. This implementation cannot
* be used for encoding validation purpose.
