FAQ
Why does a URL need encoding?
URLs only support ASCII. Chinese, spaces and special chars need percent-encoding to transmit correctly.
encodeURIComponent vs encodeURI?
The former encodes reserved chars (& = ?), ideal for parameter values; the latter keeps URL structure. This tool uses the former.
