Tabla de Caracteres ASCII

Antes de dejaros la Tabla de Caracteres ASCII es interesante conocer de donde viene este código y porqué tuvo tanta importancia.

El código ASCII (American Standard Code for Information Interchange) es un código de caracteres basado en el alfabeto latino, que el actual ANSI (Instituto Estadounidense de Estándares Nacionales) creó en el año 1963.

Es un código de 7 bits (inicialmente se empleaba el octavo bit, como bit de paridad para detectar errores) por lo tanto puede representar un conjunto de 128 caracteres (2 elevado a 7), por aquel entonces se incluyeron los códigos empleados en telegrafía.

Fue publicado como un estándar en 1967 y sus 32 primeros caracteres son de control (no imprimibles), esta es la Tabla de Caracteres ASCII

Después llegarían otros juegos de caracteres que liberarían ese octavo bit para poder codifica más caracteres, que en casi todos los casos se tratan de caracteres imprimibles.

A estos se les conoce como ASCII Extendido, y tal vez el más conocido de estos códigos sea la página de códigos 437 de IBM que implementó el sistema MS-DOS.

Estos son los códigos que incorpora desde la Tabla de Caracteres ASCII Extendido (128 al 254)
