ASCII converter FAQ

What does N/A mean?

It marks characters whose code points are outside the ASCII range of 0 through 127.

Does it support line breaks and tabs?

Yes. Control characters are converted to their ASCII decimal values too.

Is this the same as Unicode?

No. ASCII is a much smaller character set and only covers the first 128 code points.
