How to solve the problem with .htaccess?

Question

PHP

Hello!
I met with the following problem.
There is a site on Bitrix.
Today I noticed the problem of switching to the site from the Viber messenger
domen.ru/%20/?utm_source=Viber&utm_medium=Chat&utm... It gives
a 404 error.
Please help me create a rule in the htaccess redirect to domen.ru

Answer 1

So everything is true what kind of directory is this with a space name

RewriteEngine On
       RewriteCond %{REQUEST_URI} ^/\s/
      RewriteRule (.*)   /

Answer 2

Does viber put a space?

Answer 3

The redirect worked, I tried a similar entry, but the redirect happened many times and as a result the browser gave an error. And the remaining %20/?utm_source=Viber&utm_medium=Chat&utm_campaign=Private in the address bar can somehow be removed?
and there is no directory with space name ..
