Like (◠‿◠✿) or like 🌹? The first comes from characters not in an English/American keyboard. If you make it another one and learn it, then tada (or copy paste if you save the ones you likes somewhere). The red rose... you just have to find "emojis and characters" on your tablet. For mine, it's Edit --> emojis & characters --> emoji --> animals and nature. These, you'll just have to keep in mind look different on different operating systems. If you look over here (this is a link), you'll see images of how the same rose appears depending on what device/internet browser you're using.
