Hi Dubravko,

This is a known issue with metaPost and any module which truncates the text without first stripping the HTML.  This used to be an issue with the Blog module, but we updated the code to strip out the HTML before truncating.  The best solution is to use tokens which don't truncate the characters as you have described. 

When we still had this issue with the Blog module, I stopped using the auto summary feature and created my summaries manually using the split post feature in WLW. 

Hope this helps!

Don
