I have lots of content with long teasers that I am pretty happy about (I do not want to modify it), but I would like it to be displayed by one of the views truncated at a certain length.
To be more specific I would like the displayed teaser to be trimmed at last space before x chars.

I know I can 

function truncateTeaser ($teaser, $maxLength)
{
   $truncatePoint = strrpos($teaser, ' ', $maxLength);
   if  (($truncatePoint <= 0) || ($truncatePoint >$maxLength))
   {
       $truncatePoint = $maxLength;
   }
   return substr($teaser, 0, $truncatePoint);
}

possibly with some extra preprocessing if strrpos / substr offsets are not utf8-aware

But isn't there a better way?

Can someone point me in the right direction?
