I saw that many places on the Internet use characters like /u4e2d/u56fd when transmitting Chinese, which are Unicode encoded characters, and I want to know what the specific content is, but it is not easy to see, so I want to decode this character set into normal characters.
At first, I converted the encoding format through Encoding, and found that it didn't work, and I couldn't solve it normally, and then I searched for some similar decoding solutions on the Internet, which were feasible, but I found that it was a bit troublesome to write, and if I had batches of Unicode characters, I couldn't output them directly, and then I looked and looked at them, and finally, I found two methods of char classes: one is char. ConvertFromUtf32, the comment says: Convert the specified Unicode code bit to a UTF-16 encoded string, isn't this just decoding; Another is char. ConvertToUtf32, comment: This method is to convert UTF-16 encoded characters at specified positions in the string into Unicode code points, ha, in fact, it is to convert ordinary characters into Unicode character sets.
