The primary component of a String is a Character, but you probably already know that. But do you know that characters are just code representations?
I mean, the computer doesn’t know characters, letters, etc., nor does it store them as such in memory. The computer stores them as numbers (as binary, to be precise).
There are some conventions that define which number will represent which character. This character set maps some numbers or code points to textual characters.
Then, at the time of visual representation, computers read them from memory and represent them as characters based on that mapping. This mapping and character representation is called character encoding.
