Not much of an issue, since most people just turn it off... but the game will filter any word it deems a profanity, regardless of spaces, context or preceding/succeeding letters.

One instance of this is:

"There is a version update in June." coming out as "There is a version update ?? ???e."

Because "Injun" is considered offensive (For those who don't know, "Injun" was a word to describe Native Americans in like the 1800s).
