Qual é a diferença entre character e letter(not mail) ?Podes indicar apenas respostas exemplo.

Character can be a more old-fashioned way of saying letters. Character usually refers to foreign languages that use a different alphabet system.
- For example, "Today we will learn 4 new Chinese characters"

* A character also can mean a person in a fictional world, (in a book, movie, film, or a fictional work)
-"My favorite character in Marvel is Spiderman"

A letter or letter is typically what Americans and most English speakers refer to as the pieces of the English alphabet.
- For example, " Johnny is writing the letter J"
- "The letter M is my favorite letter."
- "Maria has nice lettering" (handwriting/penmanship)
