/**
* Creates a new Url object from a URI.
*
* This method is for generating URLs for URIs that:
* - do not have Drupal routes: both external URLs and unrouted local URIs
* like base:robots.txt
* - do have a Drupal route but have a custom scheme to simplify linking.
* Currently, there is only the entity: scheme (This allows URIs of the
* form entity:{entity_type}/{entity_id}. For example: entity:node/1
* resolves to the entity.node.canonical route with a node parameter of 1.)
*
* For URLs that have Drupal routes (that is, most pages generated by Drupal),
* use Url::fromRoute().
*
* @param string $uri
* The URI of the resource including the scheme. For user input that may
* correspond to a Drupal route, use internal: for the scheme. For paths
* that are known not to be handled by the Drupal routing system (such as
* static files), use base: for the scheme to get a link relative to the
* Drupal base path (like the <base> HTML element). For a link to an entity
* you may use entity:{entity_type}/{entity_id} URIs. The internal: scheme
* should be avoided except when processing actual user input that may or
* may not correspond to a Drupal route. Normally use Url::fromRoute() for
* code linking to any any Drupal page.
* @param array $options
* (optional) An associative array of additional URL options, with the
* following elements:
* - 'query': An array of query key/value-pairs (without any URL-encoding)
* to append to the URL.
* - 'fragment': A fragment identifier (named anchor) to append to the URL.
* Do not include the leading '#' character.
* - 'absolute': Defaults to FALSE. Whether to force the output to be an
* absolute link (beginning with http:). Useful for links that will be
* displayed outside the site, such as in an RSS feed.
* - 'attributes': An associative array of HTML attributes that will be
* added to the anchor tag if you use the \Drupal\Core\Link class to make
* the link.
* - 'language': An optional language object used to look up the alias
* for the URL. If $options['language'] is omitted, it defaults to the
* current language for the language type LanguageInterface::TYPE_URL.
* - 'https': Whether this URL should point to a secure location. If not
* defined, the current scheme is used, so the user stays on HTTP or HTTPS
* respectively. TRUE enforces HTTPS and FALSE enforces HTTP.
*
* @return static
* A new Url object with properties depending on the URI scheme. Call the

* Creates a new Url object for 'internal:' URIs.
*
* Important note: the URI minus the scheme can NOT simply be validated by a
* \Drupal\Core\Path\PathValidatorInterface implementation. The semantics of
* the 'internal:' URI scheme are different:
* - PathValidatorInterface accepts paths without a leading slash (e.g.
* 'node/add') as well as 2 special paths: '<front>' and '<none>', which are
* mapped to the correspondingly named routes.
* - 'internal:' URIs store paths with a leading slash that represents the
* root — i.e. the front page — (e.g. 'internal:/node/add'), and doesn't
* have any exceptions.
*
* To clarify, a few examples of path plus corresponding 'internal:' URI:
* - 'node/add' -> 'internal:/node/add'
* - 'node/add?foo=bar' -> 'internal:/node/add?foo=bar'
* - 'node/add#kitten' -> 'internal:/node/add#kitten'
* - '<front>' -> 'internal:/'
* - '<front>foo=bar' -> 'internal:/?foo=bar'
* - '<front>#kitten' -> 'internal:/#kitten'
* - '<none>' -> 'internal:'
* - '<none>foo=bar' -> 'internal:?foo=bar'
* - '<none>#kitten' -> 'internal:#kitten'
*
* Therefore, when using a PathValidatorInterface to validate 'internal:'
* URIs, we must map:
* - 'internal:' (path component is '') to the special '<none>' path
* - 'internal:/' (path component is '/') to the special '<front>' path
* - 'internal:/some-path' (path component is '/some-path') to 'some-path'
