Welcome
ASCII stands for the American Standard Code for Information Interchage.
A character is a single 1-byte value that is translated as an ASCII code into either non-printing control codes (like backspace, tab, carriage return, line feed, etc.) or into something printable (which you can see as letters, numbers or symbols on your screen).
Note that different fonts will represent characters differently; also, you need to be sure that you are using the standard character set (ISO 8859-1 Latin-1) in order to view these correctly.
Different character sets use the same numbers for entirely different characters (such as math symbols, typographical symbols, even different language alphabets altogether!). Below is a chart that lists each character's decimal value. For the control codes, it lists that code's short name and what it means; for the printable characters, it shows what the character looks like and what it is called.
| Decimal Value | Control Code | Meaning |
|---|---|---|
| 000 | NUL | $null |
| 001 | SOH | CTCP Delimiter |
| 002 | STX | Bold Text (ctrl-B) |
| 003 | ETX | Colored Text (ctrl-K)1,2 |
| 009 | HT | Tab |
| Decimal Value | Control Code | Meaning |
|---|---|---|
| 010 | LF | $lf |
| 013 | CR | $cr |
| 015 | SI | Normal Text (ctrl-O) |
| 022 | SYN | Reversed Text (ctrl-R) |
| 031 | US | Underlined Text1 (ctrl-U) |
Notes: 1. Any of these control codes can be turned off by using another one of them where you wish to turn them off. For the color code, you would simply include a $chr(3) without any numbers following it. If you want to cancel all formatting codes currently in force, use $chr(15) normal text.
2. The ctrl-k $chr(3) code must be followed by a number representing the foreground color of the text, optionally followed by a comma and another number representing the background color for that text, in the form $chr(3) $+ ##,##
