Truncate Long Titles

Your plugin is very useful to me. I would like to ask you if there is a way to truncate long titles. I tried to use the method described here: http://www.ambrosite.com/blog/truncate-long-titles-to-the-nearest-whole-word-using-php-strrpos but I was not lucky.. I added the $text = substr( $text, 0, strrpos( substr( $text, 0, 35), ' ' ) ); before the return $text; but after that I could not manually alter the slug. Do you have any good ideas about this? Thanks a lot.. George from Athens, Greece https://wordpress.org/plugins/skp-greeklish-slugs/
