ECS Extended Character Set

IBM PC Extended Character Set (ECS)

DOS uses the IBM PC Extended Character Set, or ECS for short. The lower 128 values are the same as the ASCII character set, but values 128-255 map into the European characters differently from other character sets, including that used on Windows.

One odd thing about ECS is that codes 0-31 and 128-159, which are assigned to non-printing control functions such as Return and Line feed, are also assigned special graphics for use in contexts where control functions are not needed. That is how you get happy faces and arrows in ECS displays and line-drawing characters as well as European characters. Here are the graphic symbols for character codes 1 to 31 (normally ^A, the SOH character, through ^_, the US character):
