Mathematical Alphanumeric Symbols
Appearance
Mathematical alphanumeric symbols are modifications of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles (one example is blackboard bold).
Unicode now includes many such symbols (in the range U+1D400 ... U+1D7FF). Those symbols should be used only in mathematical formulas. In general text, use standard letters with markup instead.
