📖 Complete URL Encoding Guide

🔤 What is URL Encoding?

URL encoding (also called percent encoding) is a method to encode information in URLs by replacing unsafe ASCII characters with a "%" followed by two hexadecimal digits representing the character's ASCII code.

Why URL Encoding is Essential:

Safety: Ensures special characters don't break URL structure
Compatibility: Makes URLs work across all systems and browsers
Standards: Complies with RFC 3986 URI specification
Internationalization: Supports non-ASCII characters like émojis and ñ

🎯 Common Character Encodings

Reserved Characters:

Space → %20
! → %21
# → %23
$ → %24
& → %26
+ → %2B

Special Characters:

/ → %2F
: → %3A
? → %3F
@ → %40
= → %3D
% → %25
