Emojis are symbol unicode characters that can be used to customize either smileys or text. These special characters can be added in the body of text messages or even into subject lines.
Emojis in subjects lines (email)
_/!\ Please note that Google Chrome currently does not support emojis. /!\_
Therefore, in order to be able to create/edit subject lines containing emojis, users will need to use Firefox or Internet Explorer.
Some Chrome extensions (like Chromoji or Emojify) allow to display emojis but they are not really reliable so we don’t recommend their use.
However, a lot of web-mails replace emojis with nice images (as you can see in the screenshot above). Therefore, even using Chrome, you’ll see the emojis properly displaying in Gmail when receiving your messages.
Emojis in SMS messages
You can also display emojis in SMS messages.
_/!\ Emojis count for 2 characters. /!\_
You must select the option Unicode when you write your message to allow special characters (but limited to 70 characters). If you do not select this option, emojis will not be displayed.
Be careful, some operators do not support emojis (e.g.: Bouygues Telecom in France), so you have to test your SMS message with different operators before you send it.
