.htaccess: Rewrite Problem

I'm creating a website. I have this code in the .htaccess file:

RewriteEngine On

RewriteRule ^/([-a-zA-Z0-9开发者_开发技巧_]+)/$ /redirect.php?id=$1

But when I go to, for example /ASEi it says 404 Not Found. What's the problem?

Try this instead:

RewriteRule ^/([-a-zA-Z0-9_]+)/$ /redirect.php?id=$1

I found it, the problem was the first /. The .htaccess now looks like:
RewriteEngine On
RewriteRule ^([-a-zA-Z0-9_]+)$ redirect.php?id=$1
