What does ASCII Table actually do?

The ASCII table maps the 0–127 code points to their control names or characters. It does not include Latin-1 or Unicode. Codes above 127 are not ASCII even if a font draws them.

When should I use ASCII Table?

Use it to identify a byte in a protocol or a legacy file.

When should I not use ASCII Table?

Do not use it for emoji or accented letters. Use Unicode lookup.

What does ASCII Table not do?
