Using or trying to use successfully emojis in the mail object and Adobe Campaign classic (v6/v7) is a pain at the moment.
In most cases, it doesn't work correctly, even by typing such sequence of chars:
=?UTF-8?Q?=F0=9F=8F=A2?=
By chance, if some people succede to use it (probably due to different contexts (version of AC or charset used by the AC environment), it often breaks with a mix of special characters to use.
Please find a way to ease typing emojis in the mail object field.
And don't limit such improvment to Adobe Campaign standard version, it must apply to AC v6/v7
