 * Percent encoding is used in every URL component except for the hostname. But the set of
 * characters that need to be encoded is different for each component. For example, the path
 * component must escape all of its `?` characters, otherwise it could be interpreted as the
 * start of the URL's query. But within the query and fragment components, the `?` character
 * doesn't delimit anything and doesn't need to be escaped.
