BUG: errors handling unicode emoji

[veesahni]

Router5 Version: 8.0.1
Node Version: 12.16.3

Code to reproduce bug:

      const router = createRouter({ name: 'users', path: '/users?:q' })
      console.log(router.matchPath('/users?q=test漢字'))
      // outputs: {name: "users", params: {…}, path: "/users?q=test%E6%BC%A2%E5%AD%97", meta: {…}}
      console.log(router.matchPath('/users?q=60ad50🚀'))
      // outputs: {name: "users", params: {…}, path: "/users?q=60ad50%F0%9F%9A%80", meta: {…}}
      router.setRootPath('/base')
      console.log(router.matchPath('/base/users?q=test漢字'))
      // outputs: {name: "users", params: {…}, path: "/base/users?q=test%E6%BC%A2%E5%AD%97", meta: {…}}
      console.log(router.matchPath('/base/users?q=60ad50🚀'))
      // EXCEPTION: Uncaught URIError: URI malformed

Discussion:

• Router 5 does not handle unicode emoji in path or query parameters.. but only when root path is not set
• I chased the bug down to the underlying library and raised a bug there
• Has anybody else encountered this?
