A fast three-step workflow
How to use the character frequency counter
- 1
Enter the known information
Add only the values or source text the calculation needs. Useful examples and safe defaults are already selected.
- 2
Adjust the assumptions
Use the extra controls to match your real task instead of accepting a hidden one-size-fits-all assumption.
- 3
Review the complete result
Check the main answer, supporting values and method before copying, downloading or acting on the result.
What makes this tool more useful
Reveal which characters a text actually uses, including whitespace and emoji. Sort by count or code point and export the table.
How the calculation works
The tool iterates Unicode code points rather than UTF-16 code units, preventing most emoji from being split into two counts.
Inspect encoded text, writing patterns, test data or character-set requirements.
Private, fast and mobile-ready
The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
