Sanitization of target URL not working correctly

[aKacharava]

When a URL is parsed, some characters, like ( , ; etc. are internally converted to -. If a page exists for the --ed version of the URL, that page will be shown.

For example, when visiting the URL https://example.com/about-us/, instead of typing /about-us/ you can type different special characters in between "about" and "us" and still visit the page:

• /about(us/
• /about)us/
• /about,us/
• /about;us/
• etc.

This is caused by the sanitizing function that is called on the target URL. I think this is incorrect and should be changed.
