            I realizes that such a font would require a lot of hard disk and ram
    space. The context in which i want to use it is for editing plain
    unicode text files. Text editors can't display documents in multiple
    fonts depending on which script each character belongs to. To be
    specific I want to edit test cases for a lexical analyzer generator
    that I want to be able to handle unicode.
