用htaccess重写网址

Redirect every url parameter to index.php but I have some persian language parameter in url for url friendly but I have some issue with some words.

for example :

NOT work : www.example.com/بیمه

100% work : www.example.com/تهران

It's not have any issue and it's work correcly and open index.php

RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^(.*)$ index.php

This RewriteRule is work for english lang url parameter but I see error 404 in some persian language . maybe star (*) not meaning everything in this code .

Page error is :

Object not found!

The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

Error 404
