Hello, I am laying out a book in InDesign and when I type in the letters "hn" together, as when typing the name John, the character "U" with an apostrophe above it automatically replaces the letters "HN." This also happens when I type in the letters "il" together such as in the word "filler". In this case a Y with an apostrophe above it replaces the "il". I have never seen this happen before, I have no idea what is going on. Can someone please help me??
This sort of oddity is often associated with having a second language enabled in the OS and having inadvertently changed the keyboard tot he second language. In Windows the keyboard shortcut to switch languages is one of the more common key combinations (I've forgotten which one) we use in ID for other purposes.
