It use to be pretty tough to get special characters into your text in AutoCAD. You had to use %% or other tricks to get it done. Some may still use these “inline” tricks or you could use the menus.
Ever use Unicode – I have not… but…
When entering text, you can create special characters, including the degree symbol, plus/minus tolerance symbol, and the diameter symbol, by entering the following Unicode character strings:
\U+00B0 = Degrees symbol (°)
\U+00B1 = Tolerance symbol (±)
\U+2205 = Diameter symbol
Better yet – Use %% – this is a more standard way of enter special characters
In addition to using Unicode characters for entering special characters, you can also overscore text, underscore text, or insert a special character by including control information in the text string. Use a pair of percent signs to introduce each control sequence.
You can use this control code with standard AutoCAD text fonts and Adobe PostScript fonts:
%%nnn – Draws character number nnn.
NOTE: You can use these control codes with standard AutoCAD text fonts only:
%%o – Toggles overscoring on and off.
%%u – Toggles underscoring on and off.
%%d – Draws degrees symbol (°).
%%p – Draws plus/minus tolerance symbol (±).
%%c – Draws circle diameter dimensioning symbol .
What if I want the % sign???
%%% – Draws a single percent sign (%). This is valid for the TEXT command only.
Overscoring and underscoring can be in effect at the same time. Both turn off automatically at the end of the text string.
You can use the %%nnn control sequence to display special characters using the PostScript fonts.
You can also get most of these off the MTEXT menu now.
