How to Make Hearts on Twitter
If you're a user of Twitter, a social networking site based on 140-character status updates, you can send updates (called "tweets") containing a variety of different characters, including hearts. Using a heart symbol can help you save an extra character by not having to use the "emoticon" heart (<3) and can help you better convey a message of love in your tweet. Unlike Facebook, Twitter would translate <3 just like that and would not turn it into an actual heart symbol. You can learn how to make a heart on Twitter by following a few steps.
Visit the Twitter Chat Emoticons and Smileys page at ChatSmileysEmoticons.com/characters-symbols-and-emoticons-in-twitter/.
Scroll down and find the black heart (♥) character in the list. The heart is the seventh symbol up from the bottom of the list.
Highlight the heart using your mouse, then right-click the selection and select "Copy."
Go to Twitter.com and log in to your account.
Right-click inside the status update box at the top of the page and choose "Paste." The heart will now appear in your tweet box. You can paste multiple hearts into the box if you prefer.
