High Quality Content by WIKIPEDIA articles! Mathematical Alphanumeric Symbols is a Unicode block of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles (one example is blackboard bold, called "double-struck" in Unicode terminology). Unicode now includes many such symbols (in the range U+1D400 ... U+1D7FF). The rationale behind this is that it enables design and usage of special mathematical characters (fonts) that include all necessary properties to differentiate from other alphanumerics, e.g. in mathematics an italic "A" can have a different meaning from a roman letter "A". These symbols are to be used only in mathematical formulas, not in general text.
