One way would be to add the unicode value like so:
Code: [Select]
\U+03C0In lisp you'd need to double backslash the U+.

Use Unicode, e.g.:

Code: [Select]
(defun c:test ( )
    (entmake '((0 . "TEXT") (40 . 1.0) (10 0.0 0.0 0.0) (1 . "\\U+03C0")))
    (princ)
)
Edit: Irne beat me to it :P

Is that for special SHX fonts? I get text displaying %%960 even if I use \960 it doesn't convert. Tried using ARIAL.TTF & Romans.SHX. The Unicode works on ARIAL.TTF, but only works on Romans.SHX if you turn on the "Use Big Font" check in the Style dialog.

I never explored Big Fonts but maybe they are above the normal range of character codes.
It's aggravating at times when trying to use special characters as they vary from font to font.

The thing is, if my font is Romans.SHX and I want one of these unicode characters, then 9/10 times the charcter is displayed as some TTF font (usually Arial). If I set the Romans to use Big Font, then most of these characters display correctly. So it seems that BF simply implements the UniCode in the font as well, meaning instead of only 230 od characters there could be 1000's

I've not tried the Standard.SHX much. We generally don't use it. So I can't say much about its Big Font, though I think it uses the same one as for Romans.

Maybe a font expert will help us out.  8-)
I don't have a Standard.shx and the STANDARD style gets me into trouble as it can vary from user to user & file to file.

Looks like the Big Font is a separate file.

It should create a Text object with text height 1.0 and insertion point at the origin.

At least, it does for me :)

That's due to the font you're using. It has to define the character with that unicode (hex:3C0, dec:960, oct:1700). Most of the SHX fonts only define the normal ANSI codes, i.e. dec:32/hex:20 (space) through dec:255/hex:FF (ÿ). For the characters in excess of that you either need to add the bigfont option to the style, or use a TTF font in the style instead.

Note, not all TTF fonts define all unicode characters either. The easiest way to find them IMO is to check the Character Map program in windows - that's also where I find the unicode value to input into acad.

Change to Greeks font and use lowercase P.  Greeks is native to AutoCAD.  You can also use this method to get the Ohms symbol by using uppercase W.

Good idea! So inside MTexts / Dim Overrides / MLeader texts you can place the following piece of text from Lisp:
Code - Auto/Visual Lisp: [Select]
  1. "{\\Fgreeks|;p}" ;Using the Greeks.SHX font
  2. "\\U+03C0" ;Using the unicode double-byte character code
For other stuff you can do the same, e.g. micro Ohms:
Code - Auto/Visual Lisp: [Select]
  1. "{\\Fgreeks|;mW}" ;Greek font
  2. "\\U+03BC\\U+03A9" ;Unicode
Or indicating delta:
Code - Auto/Visual Lisp: [Select]
  1. "{\\Fgreeks|;D}" ;Greek font
  2. "\\U+0394" ;Unicode

The nice thing about using Greeks.SHX is the characters look as if they are the same font as the Romans.SHX font. Where the unicode uses alternative fonts if the BigFont is not turned on. And even with BigFont turned on, I like the Greeks version more.

Greekc.shx is also rather nice:

Though it's still working, I believe to remember that Autodesk switched to unicode with Autocad2008. That's when I stopped using %%###.  BTW hex960 = dec03C0 (hint) ;)

I've never seen a different alternate font than Arial. But I just change these characters to Simplex and then you don't even notice that another font is used for these few characters.
Another thing you can try is to edit your ACAD.FMP file. If you add
Code: [Select]
Arial;ROMANEUR.shx to this file the font ARIAL should (in theory :kewl: ) be replaced with a ROMAN-font that supports the most important unicodes.

If you open a drawing and you get a message like:
Quote
' ** Undefined shape 8962 '
that means a character is used, but the used font doesn't support that special character.

Owen has made a tool to remove these characters:

CleanLanguage is intended for removing corrupt text; I could be wrong, but I don't think it would remove a missing shape reference from existing text. My SuperPurge utility can remove shape file references, though.
