How to prevent converting parameter character when reloading the current page in javascript?

Question

I use (~) character for my url parameter on my page

http://localhost:8000/clients?page=2&filter=type~active

And if I'm force to reload the page, the (~) character turn into (%) so this is my url after reloading the page

http://localhost:8000/clients?page=2&filter=type%active

I tried search this problem using the title of this question as my keyword, but the result are far from the problem.
