Unicode UICF-16 Encoding

Question

I have a wide char string - this is L "hao123-- 我 的 上网 主页" and it should be encoded in "hao123 - \ u6211 \ u7684 \ u4E0A \ u7F51 \ u4E3B \ u9875". I was told that the encoded string is a special format called "% uNNNN" for encoding Unicode UTF-16 code points. At this website , he tells me that JavaScript is running away. But I do not know how to encode it using C ++.

Is there a library there to make this work? or give me some advice.

Thanks to my friends!
