Unicode symbols
In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but can be used as part of a text.
Many of the symbols are drawn from existing character sets or ISO or other national and international standards. The Unicode Standard states that “The universe of symbols is rich and open-ended.”[1] This makes the issue of what symbols to encode and how symbols should be encoded more complicated than the issues surrounding writing systems. Unicode focuses on symbols that make sense in a one-dimensional plain-text context. For example, the typical two-dimensional arrangement of electronic diagram symbols justifies their exclusion.[2] 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. Two recent symbol genre additions are the Mathematical Alphanumeric Symbols (Unicode 3.1) and Yijing Hexagram Symbols (Unicode 4.0).
