How it works

ASCII is a seven-bit character-encoding standard with 128 values from 0 through 127. Values 0–31 and 127 are control codes; values 32–126 are printable characters. Extended 8-bit code pages are not part of standard ASCII.

Limits and assumptions

The table deliberately stops at 127. Unicode, UTF-8 multibyte encoding, and vendor-specific “extended ASCII” code pages are separate systems.
