Project has been using + (plus) in the middle of words means thin space. How PrintDraft change all the + (plus) become thin spaces (\u2009)?

Question

This line (in PrintDraftChanges.txt) will change a plus sign to a thin space if it has a non-space character on both sides:

"(?<=\S)\+(?=\S)" > "\u2009"

We could use \w (word forming character) but sometimes if a language has letters that aren’t in English words \w does not match them (especially if they are non-Roman letters).
