About String Escaping

String escaping is the process of converting special characters into escape sequences that can be safely included in string literals. Different programming languages use different escape conventions.

Why Escape Strings?

Special Characters: Include quotes, newlines in strings
Code Safety: Prevent syntax errors and injection
Data Transfer: Safely transmit strings in JSON, URLs
Unicode: Represent non-ASCII characters portably

Language Differences

JavaScript/JSON: Uses \uXXXX for Unicode
Python: Supports raw strings (r"..."), \UXXXXXXXX
C/C++: No native Unicode escapes, uses \xHH
Regex: Special metacharacters need escaping

Security Note: Always properly escape user input before including it in code, SQL queries, or HTML to prevent injection attacks.
