How to add an empty line in Description field using Workflows.

Hello guys,

I recently created a workflow that adds the new value of a Quote's Description field to the old one, in the event of an update. So if someone modifies the value of the Description, instead of overwriting it, the workflow adds it to the old one. The only problem is I haven't figured it out how to leave an empty line between the two values.

The current value the workflow applies to the Description field is this one : PRE("<Description>")+ " " + ToChar([<ModifiedDate>]) + " " +([<Description>])

Notice there is an empty space after the old description. Any ideas on how to make it a whole empty line?
