Description

The length function returns the number of characters in the string.

Although we mention characters, technically, we are talking about code points. In Unicode, a code point is usually but not always a character. Code points can sometimes represent single characters, but can also represent formatting and other non-alphanumeric characters.

For example, the character é can be the single character "e" that includes an acute accent (U+00E9), or it could be displayed as a single character but be composed of an "e" (U+0065) and a "combining" acute accent (U+0301). Visually, you cannot distinguish between the two.
