How are 4 bytes characters represented in C#

Question

How are 4 bytes chars are represented in C#? Like one char or a set of 2 chars?

var someCharacter = 'x'; //put 4 bytes UTF-16 character

Could you give an example of a '4 bytes char'? It would make your question clearer. – Latoria

@jv42, there are some UTF-16 characters which can not be represented by 2 bytes. So it is any character with code out of 2^16 – Lobo

See "Unicode and .NET" article by Jon Skeet - csharpindepth.com/Articles/General/Unicode.aspx – Manuelmanuela

I know those chars exist, providing an example would have made certain there was not a typo in the question, especially as 'char' and 'character' meanings are sometimes confusing. – Latoria

Answer 1

C# can only store characters from the Basic Multilingual Plane in the char type. For characters outside this plane two chars must be used - called surrogates.

You can also use a string literal such as:

string s = "\U0001D11E";

See UTF-16.
