Code page 437 (IBM PC)
American Standard Code for Information Interchange (ASCII) is a widely used character encoding system introduced in 1963.
The original character set, which is now referred as the standard character set was initially composed of 128 characters (7-bit code). The first 32 characters are control characters (also called non-printable characters), which are used to control data streams as well as devices such as printers. It later was expanded to support 256 characters (8-bit code) in order to provide language specific characters, various symbols, as well as box-drawing characters: elements used for presentation purposes, allowing to draw different kind of frames and boxes. The characters in the 128-255 range are referred to as extended ASCII.
Code page 437 is the original code page of the IBM PC.
The character table below is showing a pixel precise graphical representation for each character, alongside with a text description.
