Issues adding empty line to end of text variable

Thanks for the response @Gavin-Adams 

I tried that, but it seems like when doing an "Apply a regular expression" action, it interprets the
as literal instead of a new line, resulting in:

a

b

c

But, this did lead me to the solution I needed!

Since my solution is not exactly in line with my original question, I'll explain my problem in more detail. I'm using a Doc Gen action with an excel file. A few of the fields that are merged onto the excel file are setup to wrap-text and auto-adjust height as needed. Sometimes, this can result in the lower portion of the final line being cut off once generated:

The solution I was trying to arrive at was to add a blank line at the end of the variable being merged, to essentially have some padding at the bottom to prevent actual text from getting cut off.  Unfortunately, since Nintex seems to trim text variables automatically (at least in my testing), this kept removing the extra line I needed. My solution, was to add in the extra blank line (or 2) followed by a blank character that Nintex doesn't treat as white space. This prevents the trimming since the new lines are between valid characters, even though the final character is also white space. 

In this case, the character I used was a nonbreaking space, entered by using the keys [alt] + [0][1][6][0]. I was able to use Form Variables with the replace function to get the variable formatted as needed for my doc gen action: replace([Form].[Director Add],"$","
