What is the terminal code for the old square ASCII character used in the original Rogue game?
Here's a game that uses it as its main character:

The display system for the original IBM PC in text mode had a very simple memory mapping for the 80x24 text screen. You could poke values into bytes in a certain area of memory and characters would appear on the display. The characters for each byte value were determined by a video ROM which had bitmapped display characters for all 256 values of each byte. This included displayable characters for ASCII control characters (0-31).
Many contemporary printers had the same character set and could often be set into a literal-print mode where these control characters were printed rather than acted on (a carriage return would be printed as a character, it would not cause the print head to return to the left edge of the paper).

Not really, because that's a different character, apparently. The dos console doesn't recognize it when I paste it in.
Edit: Actually, it worked ok in dos, just not in Notepad with the Terminal font. – Nick – 2011-12-30T07:42:59.200

A smiley face is not a character in standard ASCII.

It would be a good question to investigate why terminals display the SOH and SOT characters as smileys, and the history in that tradition. – iglvzx – 2011-12-30T08:16:19.987
