Special Characters Problem

URLs contain only printable ASCII characters. Space, ampersand, equals - all require encoding. The rules confuse many developers, leading to broken integrations.

Encode vs Encode Component

JavaScript provides both encodeURI and encodeURIComponent. The difference determines whether your URLs work or fail silently. Always choose the correct function for your context.

Modern Standards

Internationalized domain names and emoji in URLs require special handling. UTF-8 encoding became standard. Keeping current prevents user-facing bugs.
