Well, now we got MBS Plugin functions to replace them:
MBS( "Text.Character"; Character Number )
MBS( "Text.Code"; Char )
So the function call MBS( "Text.Code"; "😀" returns 128512. If you pass that number into Text.Character like this MBS( "Text.Character"; 128512 ), you get back the smiley.
Coming soon in next prerelease of the MBS Plugin. Or email if you like to try it today.
