Display Emojis using its HTML code in a text

Question

Hi!

I was wondering if there is a way to display Emojis in a text using its HTML code (for example, bicycleEmojiCode string is the bicycle emoji in HTML). All I've found uses unicode or other code rather than HTML. This is the code I'm using right now:

 private Text textWithEmoji;
 private const string biclycleEmojiCode = "&#128692;";

 private void Awake()
 {
     textWithEmoji = GetComponent<Text>();
 }

 private void Start ()
 {
     textWithEmoji.text = biclycleEmojiCode;
 }

🚴 is not an HTML "code". It's actual a SGML / XML / HTML entity reference. Such an entity generally has the form of &XXXX; where XXXX represents the entity name. The special character # denotes a unicode character and the following numbers are simply the decimal unicode code point for the character. Instead of a decimal code point it's usually more common to use hexadecimal code points. For this you generally use &#xHHHH; in XML / HTML where HHHH is a hexadecimal number.

Of course HTML or anything related to HTML is completely irrelevant in Unity. If your used font actually supports your wanted code points you can simply use those unicode characters directly inside your code by using the proper C# unicode escape sequences. In C# you can only specify hexadecimal unicode code points. There are two ways. Either \uXXXX or \UXXXXXXXX Note that when using \u you always have to give exactly 4 hex digits when using \U you have to specify exactly 8 digits. So \u can only be used for the code points 0000 to FFFF.

The code point in question (🚴) is beyond the four digits so you have to use \U. The decimal number "128692" is "1F6B4" in hexadecimal. Since we need 8 digits we have to add 3 padding zeros:

 public const string biclycleEmoji ="\U0001F6B4";

Hi @Bunny83 thanks for the answers, I really appreciate it. I've tried using \U0001F6B4 but it always show a ? mark inside a diamond. Do you know how to solve that issue? I've Rich Text enabled and have tried different fonts that are supposed to support emoji, but doesn't seem to work :(
