Use Unicode Characters, Control Codes, and Special Characters

You can use Unicode characters, control codes, and special characters in a text string to represent symbols. (All nontext characters must be entered as their ASCII equivalent.)

You can create special characters by entering the following Unicode character strings:

Unicode character descriptions
Unicode character	Description
\U+00B0	Degree symbol
\U+00B1	Plus/minus tolerance symbol
\U+2205	Diameter dimensioning symbol

In addition to using Unicode characters for special characters, you can specify a special character by including control information in the text string. Use a pair of percent signs (%%) to introduce each control sequence. For example, the following control code works with standard AutoCAD text and PostScript fonts to draw character number nnn:

%%nnn

These control codes work with standard AutoCAD text fonts only:

Control code descriptions
Control code	Description
%%o	Toggles overscore mode on and off
%%u	Toggles underscore mode on and off
%%d	Draws degree symbol
%%p	Draws plus and minus tolerance symbol
%%c	Draws diameter dimensioning symbol
%%%	Draws single percent sign
