Converting to hex?

Question

Whenever I try to convert '™' to hex string using

string.Format("{0:X}", (int)"™");

It returns 2122 which is weird because when I use online converters I get 99. Why?

Answer 1

99 is the code for ™ in the Windows-1252 encoding, while 2122 is the code according to the Unicode standard.

Answer 2

As explained by Cito, 99 is the code for ™ in the Windows-1252 encoding. You can get it as follows:

var result = Encoding.GetEncoding("Windows-1252")
                     .GetBytes("™")
                     .Single()
                     .ToString("X");

// result == "99"
