How to make space in htaccess link?

Question

htaccess

hello, please tell me how to make a space in htaccess in the link?
there is this rule

RewriteRule ^jar /search/?country=Ярославская%20область&region=ярославль [nc,qsa]

but in my script, instead of a space, 0 appears, is it possible to somehow pass a space to the script?
instead of %20 I tried just a space, error 443 immediately

Solution: escape the space with a slash

RewriteRule ^jar /search/?country=Ярославская\ область&region=ярославль [nc,qsa]
