Emoji in Business Central ? ??

Yes, emojis can be used in Business Central from AL Code as well as from the page.

Windows + ;  
Short cut key for Windows        

Command + Control + Space
Short Cut key for Mac        

Recommending to use as only Represanation, I am not recommending using it as data, as it might affect various cases.

Expecting answers from Dynamics Community, Not sure

1. CDS integration
2. Data Upgrade
3. Filtering data with Code
4. Etc. (Please comment as per you what are the cases/process that might affect !!)

I created a table to check what size is required to store the emoji.

You can use text/Code variables if you want

Initially, i created two fields Code[1] and Text[1]

        case Rec.Blocked of
            Rec.Blocked::All, Rec.Blocked::Invoice:
                begin
                    Rec.Emoji_Text := '?';
                    Rec.Emoji_Code := '??';
                end;

            Rec.Blocked::" ":
                begin
                    Rec.Emoji_Text := '??';
                    Rec.Emoji_Code := '??';
                end;
        end;        

But Ended up with the error below

Even if there is only one emoji, we have to use a length of 2, After Changing Text[2] and Code[2] I am able to see the change.
