This is a partial screenshot from a learning app called Kinnu. The app allows the user to choose a "brain name," and the image is from the brain-name-choosing page. There are three items of interest in the image. At the top is white text, the app's, that reads "Choose a brain name." Just below that is a lozenge-shaped field in which I have typed my desired brain name, which is "Phil'sLostBrain." Finally, beneath that is red text from the app that says, "No swear words please." I'm stumped as to how the app finds a swear word in the phrase--which, I should note for the vision impaired, is all one "word," with no spaces or underscores. It does use an apostrophe in "Phil's." So, "Phil'sLostBrain." Where the swear?

Will some kind soul help me out, please? I'm stumped.
