Interesting Autocorrect

I was going to post a message that mentioned famed test Pilot ChuckYeager.... but then, when viewing prior to posting, I noticed the forum software had changed his name to "a famous test pilot". The first example worked because I did it without a space between the names, the text in the quote came from inserting his name with a proper space between first and last.

I am amused. Can we ask why this is set up this way? Is there some dirty connotation to his name that I'm naively unaware of?
