RewriteRule为url链接

RewriteRule    ^article/?$    weq_page.php    [NC,L]    # Handle requests for "blog"

This rule works fine by replacing the actual page with article like this: site.com/article the page loads fine. Then i wanted to display the actual article link; i wrote this rule:

RewriteRule ^article/([\w-]+)$    weq_page.php?title=$1

Also this rule works fine. But there is a problem i found and is bothering me alot.

Take this example of the article title: site.com/article/Proposed-Argument-for-the-Treatment-of-Diabetics This link will load okay

BUT if the link has lets say: site.com/article/Proposed-Argument-for-the-Treatment-of-Diabetics.

This link will give me a page not found because the article title has a full stop(.) at the end.

Even if the title has:{&,?,:,;,,}, will give me a page not found.

Is there any way to write a rule that will allow all the above if available at any title, the web page loads okay?
