Another approach would be to implement a class "FontAwesome.cs" and then fill it with static variables:
public class FontAwesome
{
public static string FAGlass = "\uf000";
public static string FAMusic = "\uf001";
public static string FASearch = "\uf002";
public static string FAEnvelopeO = "\uf003";
public static string FAHeart = "\uf004";
public static string FAStar = "\uf005";
public static string FAStarO = "\uf006";
public static string FAUser = "\uf007";
public static string FAFilm = "\uf008";
public static string FAThLarge = "\uf009";
public static string FATh = "\uf00a";
public static string FAThList = "\uf00b";
public static string FACheck = "\uf00c";
public static string FATimes = "\uf00d";
public static string FASearchPlus = "\uf00e";
...
}
Then whenever needed, you can access it in your xaml with:
<Label Text="{x:Static fontAwesome:FontAwesome.FABriefcase}" />
Note that this requires you to include the class in your Xaml:
xmlns:fontAwesome="clr-namespace:MyApp.Globals;assembly=MyApp"
