If you are doing this to fill and justify text, I seem to remember
a research result stating that filled text (with smooth left and right
margins) works well for proportional fonts, but decreases readability
for fixed pitch fonts, where ragged right (or ragged left) works better.
Sadly, I have no idea where I read that as it is only in the recesses
of my somewhat addled brain.
