Return code point of characters in C#

Question

How can I return the Unicode Code Point of a character? For example, if the input is \"A\", then the output should be \"U+0041\". Ideally, a solution should take care of sur

Answer 1

The following code writes the codepoints of a string input to the console:

string input = "\uD834\uDD61";

for (var i = 0; i < input.Length; i += char.IsSurrogatePair(input, i) ? 2 : 1)
{
    var codepoint = char.ConvertToUtf32(input, i);

    Console.WriteLine("U+{0:X4}", codepoint);
}

Output:

U+1D161

Since strings in .NET are UTF-16 encoded, the char values that make up the string need to be converted to UTF-32 first.
