ASCII Table Reference

No — only the standard 0-127 range, which is universally defined the same way everywhere. Codes 128-255 vary by encoding (Windows-1252, ISO-8859-1, etc.) and aren't part of the original ASCII standard, so including them would need picking one specific encoding.

The character itself (like "A"), its decimal code (like "65"), its hex code (like "41" or "0x41"), its octal code, or a control character name/abbreviation (like "newline" or "BEL").

They're non-printing characters (like line feed, tab, or escape) that control text formatting or communication rather than displaying a symbol — so a short name is more useful than trying to render an invisible character.

Yes — ASCII is a much smaller, older 128-character subset that Unicode (which covers over a hundred thousand characters across every writing system) fully includes as its first 128 codepoints. If you need characters beyond basic English letters, digits, and punctuation, you're looking for a Unicode reference instead.
