Systems and arrangements are provided for filtering language. As presently preferred, these are configured to filter inappropriate language, symbols, words, etc on web sites or used in chat rooms. Embodiments create one or more arrays of inappropriate character strings representing, for example, obscene words and character combinations. Embodiments identify the inappropriate character strings, for example in chat text, and edit them to an appropriate form, for example with cartoon characters, and/or delete the inappropriate character strings. Preferably, at least one embodiment applies the content filter via executing a program of instructions, stored on a tangible storage medium, to achieve this functionality.
