Only show the first 20 characters of the blog title

Hey wordpressers,

For a certain bloglist I need to shorten my titles to 20 characters.

I’ve been using this great plugin Limit-post to only show 120 first characters for every post. All it requires is nothing more then:
<?php the_content_limit(120); ?>

I was wondering if there is something like this for the post title? I’m not an advanced php coder so I hope some people might find the time adding a few things?

Peace ??
