The 7-bit ASCII character set, including control codes. DO NOT USE for binary-coded decimal; consider using [character-sets] instead for extensions of ASCII. See tag wiki.

The American Standard Code for Information Interchange is a 7-bit character encoding. It represents the US variant of the ISO-646 standard, aka International Alphabet No. 5 (IA5).

Do not use this tag for binary-coded-decimal (even if some Intel instructions call it "adjust for ASCII"); for that use instead.

For extensions and modifications of ASCII, using instead may be more appropriate.
