Los códigos de ASCII extendido, del 128 al 255, se asignan a conjuntos de caracteres que varían según los fabricantes de computadoras y programadores de software. Estos códigos no son intercambiables entre los diferentes programas y computadoras como los caracteres ASCII estándar.
Por ejemplo, IBM utiliza un grupo de caracteres ASCII extendido que suele denominarse conjunto de caracteres IBM extendido para sus computadoras personales. Apple Computer utiliza un grupo similar, aunque diferente, de caracteres ASCII extendido para su línea de computadoras Macintosh. Por ello, mientras que el conjunto de caracteres ASCII estándar es universal en el hardware y el software de los microordenadores, los caracteres ASCII extendido pueden interpretarse correctamente sólo si un programa, computadora o impresora han sido diseñados para ello.
Información Importante
Los códigos ASCII extendidos pueden variar según la codificación utilizada. La tabla muestra los caracteres más comunes utilizados en la codificación ISO-8859-1 (también conocida como Latin-1), que es ampliamente compatible con sistemas en español y otros idiomas de Europa occidental.
