How to combine multiple strings into unicode?

Question

Hi!
Question: How do I combine three strings into one AND use it as Unicode? The need for \ messes everything up.

string prefix = @"\U0001F0";
string hexSuit = "A";
string hexValue = "B";     
        

I want to put together these three strings into "\U0001F0AB" that's actually usable as Unicode in C#.
Is there a way to do this?

Background: I'm making a card game in Forms. It will have two enums, Suit and Value, for the cards, which I convert to hex in order to get the corresponding character in Unicode (page two: [https://www.unicode.org/charts/PDF/U1F0A0.pdf although I will use 52 cards, not 56)

In the example above, (int)suit equals 10, which gets converted to A in hex, and (int)value equals 11, which is B in hex. This gives me the Jack of spades character. Everything works as expected when hardcoding "\U0001F0AB" into Form1.
I know I could solve this with an x52 Switch, or just use images, but I haven't given up this just yet.

    public enum Suit
    {
        Spades = 10,
        Hearts,
        Diamonds,
        Clubs
    }


    public enum Value
    {
        Ace = 1,
        Two,
        Three,
        Four,
        Five,
        Six,
        Seven,
        Eight,
        Nine,
        Ten,
        Jack,
        Queen,
        King
    }

Try one of possibilities:

public enum Suit
{
    Spades = 10,
    Hearts,
    Diamonds,
    Clubs
}

public enum Value
{
    Ace = 1,
    Two,
    Three,
    Four,
    Five,
    Six,
    Seven,
    Eight,
    Nine,
    Ten,
    Jack,
    Queen = Jack + 2, // MODIFIED
    King
}


// example

Suit suit = Suit.Spades;
Value value = Value.Ace;

Int32 u = 0x00010000 | ((((0xF0 << 4) | (int)suit) << 4) | (int)value);

string result = char.ConvertFromUtf32( u );
