Symbols are often encoded in Unicode formats to provide a standard glyph for use as a font. See ISO-8859-1 for symbols below 256 (U+100) and special characters for sample values above 256. See also Named character references for HTML5 supported codes.

[edit] Categories

The series range is shown, however, many symbols are already present in fonts outside the ranges shown here.

  • Currency symbols - alternate glyphs are not supported, except by font variation. U+20A0..U+20CF codes symbols not found embedded in other locations. Small font variants are between U+FE50..U+FE6F
  • Technical symbols - generally control codes U+2400..U+243F, U+2300..U+23FF

    • music notation U+02669..U+0266F, U+1D100..U+1D1E8
    • poetry and lyrics metrics - U+23D1..U+23D9
    • dental notation - U+23BE..U+23CC
    • electrical notation - U+238D..U+2394, U+23DA earth ground and U+23DB fuse

[edit] Special forms

  • Combining marks may also be used for symbols. especially U+20D0..U+20FF
  • Dingbats and optical character recognition characters are different from all other characters in the standard, in that they are encoded based primarily on their precise appearance. U+2440..U+245F
