| The symbols have the correct Unicode mappings and are also mapped to characters in the 128 through 255 range so they can be used by applications that do not support Unicode, such as Chief Architect. In addition the font has six special symbols often used in architectural and site plan drawings, including the diameter or null set symbol, white square with vertical line symbol, center line symbol, angle symbol, Greek capital letter delta or increment symbol, and perpendicular or up tack symbol. |
