Code Page 437. The original IBM Personal Computer character set, a superset of the ASCII character set, can be represented using the UNICODE character set. This is the character set that is used in ANSI art or 437 art files and some ZIP archive descriptions (.NFO or FILE_ID.DIZ) held over from the MSDOS era.

The box drawing (0xB0 to 0xDF) symbols are meant to be used in monospaced fonts using the HTML TT or PRE tags or by using the corresponding CSS font style.

HOWTO Display 437 art on non MS-DOS displays
The GNU recode utility is perfectly capable of converting cp437 to many alternate formats:

  • recode cp437..html produces HTML 4.0 entities as per the table below (except for control codes). Just add a PRE and TT tags and you're good to go!
  • recode -g cp437..L1 produces ISO 8859-1 suitable for most modern OSes.
NU2's Screen to HTML(www.nu2.nu/scr2htm) can convert full ANSI Art with colors into an HTML file. ACiDDraw (www.acid.org) and pablodraw(pablodraw.sourceforge.net) can display or edit files on Win32 PCs.
