A simple jQuery / regrex solution could look like the following, if you add the class "noWidows" to the tag of any element that contains text you are worried about.
Such as:
This is a very important body of text.
And then use this script:
$('.noWidows').each(function(i,d){
$(d).html( $(d).text().replace(/\s(?=[^\s]*$)/g, " ") )
});
This uses regex to find and replace the last space in the string with a non-breaking character. Which means the last two words will be forced onto the same line. It's a good solution if you have space around the end of the line because this could cause the text to run outside of an element with a fixed width, or if not fixed, cause the element to become larger.
