The character is likewise formatted as in the symset file. Some of the ways to format it:[1]
- a single literal character
- a single literal character inside single quotes
- an escape code of the form \o000 for octal
- an escape code of the form \x00 for hexadecimal
- an escape code of the form \000 for decimal
(If you know the rules for character constants in the C programming language, you might notice these rules are slightly different.)
Example: any of these lines sets the boulder to display as 0.
- SYMBOLS=S_boulder:0
- SYMBOLS=S_boulder:'0'
- SYMBOLS=S_boulder:\o060
- SYMBOLS=S_boulder:\x30
- SYMBOLS_S_boulder:\048
Non-ASCII characters will display according to the character set that the terminal or graphical system supports.
