## Use of Emoji in Xamarin.Forms 🤓🤔👨 🤹
Emoji is represented by a single Unicode character or a specific sequence of Unicode characters.
For example , 🤔 is represented by `U+1F914`.
The full list of emojis can be found [here](http://www.unicode.org/emoji/charts/full-emoji-list.html).
## Static use in XAML
Since XAML is an XML-based markup language, we have to use XML escape character `` and we have to replace `U+` prefix by `x` for each part of our emoji :
`U+1F914` become `🤔` :
```xaml
```
## Use Binding
if you want to use Data Binding to display emoji, let’s define a class that will represent emoji:
```csharp
using System;
using System.Text;
namespace EmojiInXaml.Models
{
///
/// Emoji class.
///
public class Emoji
{
readonly int[] codes;
public Emoji(int[] codes)
{
this.codes = codes;
}
public Emoji(int code)
{
codes = new int[] { code };
}
public override string ToString()
{
if (codes == null)
return string.Empty;
var sb = new StringBuilder(codes.Length);
foreach (var code in codes)
sb.Append(Char.ConvertFromUtf32(code));
return sb.ToString();
}
}
}
```
It requires a single Unicode character or sequence of characters as an input and simply overrides the `ToString` . Please note that `U+` prefix should be replaced with `0x` to specify hexadecimal notation.
**Example of usage**
// person biking => http://www.unicode.org/emoji/charts/full-emoji-list.html#1f6b4
```csharp
string bikingEmoji = new Emoji(0x1F6B4).ToString(); // 🚴
```
```xaml
```
