How to set Unicode character as Content of Label in the code-behind?

I have a Label that looks the following:

<Label Name="FalsePositiveInput" Content="&#x2713;">

This works but how can I do it in the code-behind? I tried this but obviously it's not working:

FalsePositiveInput.Content = "&#x2713;";

The character i want to display is a check mark symbol

Just one remark: If you want to use extended Unicode, you need to use not \u, but \U and 8 characters, e.g. to display left-pointing magnifying glass (1F50D http://www.fileformat.info/info/unicode/char/1f50d/index.htm) you need to use:

this.MyLabel.Text = "\U0001F50D";

Alternatively as was suggested you can paste right into your source code and then you don't need comments like "//it is a magnifying glass", but then you will have to save your source code in Unicode, which is probably not what you want.

just copy and past caractor from here

https://en.wikipedia.org/wiki/Template:Unicode_chart_Arrows

then your text in xamal looks like this

<Button Text="← Bla bla" >

+1 for Dario,

If it's a check mark symbol you need just copy it from another source into your code.

Easily found on wikipedia for instance.

Here they are : ✓, ✔, ☑

Taken from : https://en.wikipedia.org/wiki/Check_mark

Use a unicode escape sequence, rather than a character entity:

FalsePositiveInput.Content = "\u2713";

Return Check symbol This works in the code-behind and report :)

public static string FormatValue(object value, string format)
    {
        if (value == null) return "";           

        Type type = value.GetType();

        if (type == typeof(bool))
        {
            if (string.IsNullOrEmpty(format))
            {
                if ((bool)value)
                {
                    return "Yes";
                }
                else
                {
                    return "No";
                }
            }
            else
            {                    
                if ((bool)value)
                {
                    return ((char)0x221A).ToString(); 
                }
                else
                {
                    return "";
                }
            }
        }


        return value.ToString();
    }

If the character is constant and know at compile time, I'm pretty sure you can simply write the character as-is in the source code file, without encoding it as HTML entity. In other words, source files can be Unicode-encoded and Visual Studio will take care of that (or at least it does for me).
