"🔠🔡" refers to the symbols commonly known as "uppercase" and "lowercase." These symbols represent the different forms of letters in the alphabet. They are used to differentiate between capital or majuscule letters (🔠) and small or minuscule letters (🔡). The tittles, on the other hand, are the small dots or strokes that appear above certain letters, such as the lowercase 'i' and 'j'.
