Unicode escape
A Unicode escape is source-code or string-literal notation that represents a Unicode character by specifying its code point with an escape marker and hexadecimal digits.
Modern C
A Unicode escape sequence is a C escape notation using \u or \U followed by hexadecimal digits to specify a Unicode code point.
- How it is used
- Specifies Unicode characters in C string-literal macros used to draw borders.
- How deep it goes
- Defines the notation through concrete escapes but does not detail their encoding in printed multibyte strings.
- Examples
- Shows escapes for vertical and horizontal bars and two corner characters.
- What you can do after
- Evaluate/understand how an escape names a character without itself ensuring that multibyte printing works.

A Unicode escape is a string-literal notation that represents a Unicode character using a hexadecimal code point.
- How it is used
- Uses hexadecimal escapes to print Unicode characters directly inside string literals.
- How deep it goes
- Defines the syntax and demonstrates conversion through u32, but does not develop Unicode encoding internals.
- Examples
- Shows 행, H, 居, and い as characters, hexadecimal values, and Unicode escapes.
- What you can do after
- Apply it via Rust string literals to print selected Unicode characters from hexadecimal code points.
