Recently, I was entering the weather for a blog post. I just type my weather in manually when I want to include it. It was for a review of a book that took place in a region where they use Celsius, so I decided to include my current weather in Fahrenheit and Celsius. In the Apple Weather app, I tapped the option to change between Fahrenheit and Celsius. It was then that I noticed that ℉ and ℃ were not just a regular F and C with the degree° sign symbol, but their own unicode special character.
