The thinker's pose: Thoughtful face with the characteristic hand on the chin. Puts a statement, a person's intelligence, or an idea into question. Is mulling over something or thinking about a brilliant idea.
The thinking face emoji was introduced in 2015 and released as part of the Unicode 11.0 standard. This emoji can be found under the smileys and emotions
category. Because the thinking face emoji has been around for quite some time, it should display correctly in the majority of operating systems.
