Emoji vs. text symbols
Emoji are drawn in color by your device, so the same emoji looks slightly different on an iPhone, an Android phone, and Windows. Text symbols like โฅ, โ and โ take the color of the text around them instead; you can find them on the other copy and paste symbol pages.
Typing emoji without copying
On Windows, press Windows key + period (.) to open the emoji panel. On a Mac, press Control + Command + Space. On phones, switch to the emoji keyboard with the smiley key. Heart emoji have their own page: heart symbols and heart emoji.
