If I have a tag named C#, the url is http://localhost:1313/tags/c#/, this url show 404 page.
# sign in url is Special characters. Then I change the # to %23 in address bar. Then it works.

My question:
Does Hugo should generate the correct url, if url has Special characters ?
Or, do I need optimize it in my theme ?
Or, Is there any other way to change the tag “C#” link?
Thank you!
