I write a regular expression so that it works when using the term Persian. I'm using the following code but the following code does not work.
RewriteRule ^test/([0-9]+)/([\u0600-\u06FF]+)/?$ test.php?id=$1&title=$2 [NC,L]
Why not just match for everything? I'm not sure the - character range works the way you're using it:
RewriteRule ^test/([0-9]+)/(.+?)/?$ test.php?id=$1&title=$2 [NC,L]
