Description
Currently, the percentage character creates multiple issues and inconsistencies. This is partly due to:
- the
%is forbidden as part of the pathname in the URL per its spec (https://url.spec.whatwg.org/#path-state) if not escaped - IE allows it because it follows a different spec (https://tools.ietf.org/html/rfc3986#section-2.4)
In Vue router, we have multiple inconsistencies between asterisk path, param paths and regular path regarding escaping these characters and whether the navigation is initial or triggered by a push/router-link
Given this set of routes in history mode
[
{ path: '/foo/:p', component: Foo },
{
path: '*',
component: Other,
},
]History mode / Chrome, IE 11,10
