You can tell it not to do that, but then the setting affects all nodes. You'll also have to change the replacement character to +.

Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L. King, Jr.

From: Joel Willers

I’m using Pathauto. It does annoying things like removing the periods in titles, so Dr. Martin L. King, Jr. turns into dr_martin_l_king_jr which, then, can’t be used as a Title Argument in Views. Every avenue I’ve explored so far has been a bit of a failure.
