What is a backslash character?

How are universal characters represented in a string?
In character literals and native (non-raw) string literals, any character may be represented by a universal character name. Universal character names are formed by a prefix \\U followed by an eight-digit Unicode code point, or by a prefix \ followed by a four-digit Unicode code point.
When to use universal character names and escape characters?
Universal character names and escape characters allow you to express any string using only the basic source character set. A raw string literal enables you to avoid using escape characters, and can be used to express all types of string literals.
Do you have to have all eight digits to make a universal character?
All eight or four digits, respectively, must be present to make a well-formed universal character name. C++. char u1 = ‘A’; // ‘A’ char u2 = ‘101’; // octal, ‘A’ char u3 = ‘x41’; // hexadecimal, ‘A’ char u4 = ‘u0041’; // u UCN ‘A’ char u5 = ‘U00000041’; // U UCN ‘A’.
