Door

This emoji is not particularly popular, but it is used by people of all ages. It is most commonly used on Twitter, Instagram, and Facebook. This emoji is not considered rude, but it can be used to convey a sense of privacy or security.

The history of this emoji is relatively recent. It was first introduced as part of Unicode 6.0 in 2010, and was later added to Emoji 1.0 in 2015. It is one of the few emojis that has remained largely unchanged since its introduction, with the only difference being the addition of a second variation in 2018. This second variation features an open door, which can be used to represent openness or welcome.
