Emoji and Field name shortocode don’t support

in confirmation message, i want to show some emoji like this:
Thanks Dear User [x]. 💖 we have sent you an email 📧
when I save and refresh the page, all emojis disappear. it does not support emoji in editor,
also i want to add fields shortcodes with label name, for example I have Field Name “Address” then smart tags only add its [ID} not field name, hence i make confirmation template each time for confirmation message like this
First Name: [x]
Last Name : [x]
Email: [x}

is there any method to add short code with field name?

i found method in documentation [ x show=”field_label”] but each time i have to write this code for each fields ids to make a confirmation template.
