FAQs
Does this support special characters and emoji?
Yes — characters beyond the standard ASCII range are converted using their full Unicode code point, so accented letters, symbols, and emoji all produce a valid numeric code.
What's the difference between ASCII and Unicode code points?
ASCII covers only the first 128 code points (0-127), while Unicode extends far beyond that to cover virtually every character and symbol. This tool outputs the underlying code point for each character, which matches ASCII for standard English text.
Does this tool also decode ASCII codes back to text?
This page is encode-only, for a simpler, focused experience. Use our separate ASCII to Text tool if you need to convert ASCII code values back into plain text.
