Removing whitespaces or %20 in url using htaccess - php

Question

hi guys can you help me here im having a little trouble here im tring to use the htaccess to remove all 20% in my url and replacing it with hyphen I manage to get rid the other 20% in between the words Acer,Liquid,S1,S510
here is my url /localhost/gadgets/product/Acer-Liquid-S1-S510%20Mobile
As you can see there is one %20 in last part, how can I remove it
And here is my htaccess
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /gadgets/
Options -Indexes
RewriteRule ^brand/([a-zA-Z]+)$ brand.php?id=$1
RewriteRule ^product/([A-Za-z0-9-]+)/?$ product.php?product_name=$1-$2 [NC,L]
RewriteRule ^(.*/|)[\s%20]+(.+)$ $1$2 [L]
RewriteRule ^(.+?)[\s%20]+(/.*|)$ $1$2 [L]
RewriteRule ^([^\s%20]*)(?:\s|%20)+(.*)$ $1-$2 [L,R]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

Try this:
Options +FollowSymLinks -MultiViews -Indexes
RewriteEngine On
RewriteBase /gadgets/
RewriteRule ^([^\s%20]*)(?:\s|%20)+(.*)$ $1-$2 [N,E=Redirect:1]
RewriteCond {ENV:Redirect} ^1$
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R,L]
RewriteRule ^brand/([a-zA-Z]+)$ brand.php?id=$1 [NC,L]
RewriteRule ^product/([A-Za-z0-9-]+)/?$ product.php?product_name=$1 [NC,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
The first rule removes all the whitespaces in a loop (using [N]) so we don't have to specify multiple RewriteRules doing it one by one now.
The next rule (with {ENV:Redirect} condition) is optional and is used to reflect the use of hyphens on the client's browser as well so that any bookmarks created link to the correct non-whitespaced version of the URL.
