You can use Unicode characters, control codes, and special characters in your 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
In a VBA text string, this example would be entered as
Dim percent as Long
percent = ASC("%")
TextString = chr(percent) + chr(percent) + "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 |
