Thank you. Your answer and the pointer helped me a lot to understand.
So, up to my understanding...
There are few exceptional cases, for example, special characters or encoded
characters in those URIs. Also, there are some corner cases that are not
clearly defined about what `Path` expects.
Nevertheless, the baseline is fully qualified URI with unescaped characters
or the unescaped path part in URI as the documentation says but there may be
some variants.
