Valid URL fragment (#) for valid characters

Question

After some digging on the Internet, I was not able to find a good answer for what characters I can use for the URL fragment. I am writing a javascript script that will use URL fragments.

I wanted to make the URL easy to view without having it too complicated. So I was wondering if I can use characters like ":,?" Or "!". in the url fragment and still have it.

My URL fragment should contain the following values:

• order by
  • identifier
  • desc or asc
• way
  • // full / ran / path / here /
