Convert UTF-16 to UTF-8 under Windows and Linux, in C

Question

I was wondering if there is a recommended \'cross\' Windows and Linux method for the purpose of converting strings from UTF-16LE to UTF-8? or one should use different method

Answer 1

#include 

wchar_t *src = ...; // or char16_t* on non-Windows platforms
int srclen = ...;
char *dst = ...;
int dstlen = ...;
iconv_t conv = iconv_open("UTF-8", "UTF-16");
iconv(conv, (char*)&src, &srclen, &dst, &dstlen);
iconv_close(conv);
