How URL Encoding Works
Carrying characters URLs can't use
URLs allow only certain characters. URL encoding replaces the others with '%' plus a number so they travel safely.
What you'll learn from this poster
- Why it's neededOnly some characters allowed / Spaces and Japanese can't be raw / ? & = have special meaning
- Percent-encoding% + two hex digits / space -> %20 / Each character by UTF-8 bytes
- ExamplesA Japanese char -> %E3%81%82 / space -> %20 / # -> %23
- Where it's usedSearch keywords / URLs with Japanese / Form submissions
Unusable characters travel as % + number
