The massification and popularity acquired by emoticons has generated a new way of communicating moods, feelings, reactions and even complete sentences. However, despite having the same Unicode encoding, its interpretation is subject to different cultural contexts depending on the environment of the person who uses them. This time it’s the turn of the smiley face with hearts.
The emoji belongs to the yellow faces section of WhatsApp and it is a face that shows tiredness since it has closed eyes and some letters zZzZz … which has a global meaning sleeping.
Given that the emojis currently used for any application were created in a Japanese environment, its semiotics is strongly linked to this culture, you can even notice the uniqueness in the design since its inception, it is heir to a tradition of pictographic writing that is it goes back millennia in time, to the Egyptian hieroglyphs or the ideograms used to write Chinese and Japanese.
This emoticon as mentioned above has its eyes closed and its mouth open letting out three cartoon-style zzzs above its head saying that it is sound asleep. ZZZs appear blue or purple on most platforms. This emoji can also be used to represent boredom. It is generally used instead of Face Sleepy to convey sleepiness or drowsiness. Sleeping Face was approved as part of Unicode 6.1 in 2012 and added to Emoji 1.0 in 2015.
