, and other writing systems. Typically Unicode has sought to encode symbols that have clear roots in national and international standards. Similarly, it focuses on symbols that make sense in a one-dimensional plain text context. For example, Unicode cites the typical two-dimensional arrangement of electronic diagram symbols as the reason for not including those in the characters set . Of course for adequate treatment in plain text, symbols must also be largely monochromatic. Even with these limitations — monochromatic, one-dimensional and standards based — the domain of symbols is potentially limitless. Unicode has primarily focused on writing systems, Unihan ideographs and numerals. Two recent symbol genre additions are the Mathematical Alphanumeric Symbols (Unicode 3.1) and Yijing Hexagram Symbols (Unicode 4.0).
