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 is nonetheless available for use 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] (Box-drawing characters are a partial exception, for legacy purposes, and a number of electronic diagram symbols are indeed encoded in Unicode's Miscellaneous Technical block.) For adequate treatment in plain text, symbols must also be displayable in a monochromatic setting. Even with these limitations  monochromatic, one-dimensional and standards-based  the domain of potential Unicode symbols is extensive. (However, emojis  ideograms, graphic symbols  that where admitted into Unicode, allow colors while the colors are not standardized.)
