I'm searching for a method to convert a two Byte UNICODE or a variable (1-3 Byte) UTF-8 string to Chinese Simplified (GB2312). I found a lot of methods for php, Java, C# and Windows but nothing for standard "C".
Right now, my best solution is to translate this JavaScript example: https://gist.github.com/19317362/a1d8e40bfb6587463d4d
Thanks in advance!
As Remy Lebeau mentioned, I used the C-compatible library iconv.
