How do I display “Android backspace” - ⌫ in Label

问题

I have a Xamarin application with a Label which is Bound like so:

<Label Text="{Binding BackSpace}"/>

and a property in my viewmodel like so:

public string BackSpace
{
   get
   {
        ResourceManager temp = new ResourceManager("MyProgram.ResourceStrings", typeof(MyClass).GetTypeInfo().Assembly);
        result = System.Text.RegularExpressions.Regex.Unescape(temp.GetString("Backspace"));
   }
}

now I have an element in my ResourceStrings called Backspace and I am trying to get the string associated with this key which I want to be the Android Backspace - ⌫

So initially I set the resource equal to the symbol ⌫ but this just gives me a label containing ?

Now I try set it equal to the HTML hex code from here: ⌫ but this gives me ⌫

How do I get my label to display the ⌫ symbol?

PS. - Even if I try:

<Label Text="⌫"/>

I get a blank label

回答1:

You'll need to change your label's font to a font which contains backspace as glyphicon.

You'll need two things:

• Appropriate font. Probably Noto Sans Symbols https://www.google.com/get/noto/#sans-zsym. ⌫ symbol
• Label renderer which allows custom fonts. See here: https://github.com/XLabs/Xamarin-Forms-Labs/wiki/ExtendedLabel

This Xamarin link will provide more infomation on working with Fonts
