Character codes are the lowest common denominator of computing, which makes this useful for debugging encoding problems, writing escape sequences, teaching how text is stored, and solving CTF or coursework exercises. Non-ASCII characters such as emoji produce Unicode code points, and those are shown as-is so you can see exactly what is being encoded.

- Debugging character-encoding issues.
Tips for the best result
- Use the latest figures you have - even a small change in rate or term can shift the outcome by hundreds.
- For annual figures, divide by 12 to get a monthly number you can compare with the result.
- Bookmark this page and revisit the calculation as the inputs change.
Frequently asked questions
Does it handle Unicode and emoji?
Yes. The converter uses Unicode code points, so emoji and accented letters are encoded too, shown in hex with more than two digits where needed.
Which separators can I use?
Space, comma, comma with space, or none. Codes separated by any non-numeric characters are accepted on the decode side.
