Summary  
The chapter explains how to use the Kotlin Char type to represent single characters (declared with single quotes) and how to use escape characters (like `\n` and `\t`) to control formatting.  

General domain of usage  
Text formatting and printing

The `Char` type in Kotlin is used to represent a single character. You declare a `Char` variable using single quotes around the character, such as `'A'` or `'1'`. Unlike `String`, which can hold multiple characters, a `Char` always holds exactly one character. Valid `Char` values include letters, digits, symbols, or special escape characters.

Escape characters allow you to represent special characters in a `Char` value using a backslash (`\`). For instance, `\n` represents a newline character, and `\t` represents a tab. In the code above, `val newLine: Char = '\n'` assigns the newline character to a variable, and `val tabChar: Char = '\t'` assigns the tab character. When you print these characters, they control formatting in the console output rather than displaying as visible symbols.
