# Special Characters

Some fonts include special characters which are not assigned to a key on the keyboard. These symbols can be used by means of the SISCAD-P function GETCHAR:

> All characters of a textfont are numbered from 0 to 255. The GETCHAR function will produce the character of the current font corresponding to the input number. The font in use is either preset in the default file siscadp.def or defined in a CAD command via parameter FNT.
> Example (STAEDTLER MARS-head): In font `dinB` (file din6776b.fnt) you will get on given number 64 the symbol MARS-head (STAEDTLER corporate logo). By command
> CREATE TEXT L TXT=CONVN2T(''line for line it's ''; ZEICHEN(64) ;'' STAEDTLER'');PNT=<pos>;TFO=''dinB''!
> this symbol together with the STAEDTLER line concatenated will be displayed on the graphic window.

To generate symbols as well as complete fonts for your own please use the command

> CREATE TEXTFONT (= character of a textfont).

In the appendix the numbers and the corresponding symbols are listed for all fonts.
