Frequently asked questions
Why does the tool warn about codes above 127?
Because they are outside standard ASCII. They are decoded as Unicode code points so you still get a useful result, but the warning tells you the data is not really ASCII – which usually means it came from a different encoding.
What does the control character naming option do?
Rather than inserting an invisible byte into the output, it writes a bracketed label such as [LF] or [TAB]. That makes it possible to see exactly where line breaks and tabs sit in the data.
Can I mix bases in one input?
No – all values must share the base you select. Mixed input would be ambiguous, since "10" is a valid number in every base but means something different in each.
