Comment (by thudfactor):

 Hey, I managed to do something like this by stringing a few things
 together. You encode the tags, trim the string, decode the tags, then run
 WP's force_balance_tags (
 http://codex.wordpress.org/Function_Reference/force_balance_tags ) to make
 sure any tags closed on the wrong side of the trim are balanced.

 For example:

 {{{
 force_balance_tags(html_entity_decode(wp_trim_words(htmlentities($text))));
 }}}

 My real-life use case for this is outputting an "excerpt" of an ingested
 RSS feed in a template.
