Why Do I See Pipes and Squares in the Project Tab?

Pipes, squares, and questions marks (?) display in place of characters which the system has not yet been configured to display. A font that does not support the language is being used in the dialog boxes and menus. Whether or not you see pipes or squares depends on what font is used and what language you are trying to display.

You must configure your system and make sure that you have set the regional settings.
