You are going to have to define exactly what you want to do rather more clearly: your example is spacing individual characters, not words - and a regex to do that would be very different from a "genuinely word based" solution.

What is the result for 5st5s34>5 ?

It would be easier just to copy the characters one at a time into a new string, following each one by a space.
