How to use Analyze Unicode
- 1. Paste the text to inspect. Drop any string into the input pane, from a single emoji to a paragraph mixing scripts. The tool reads it immediately and starts computing statistics.
- 2. Read the breakdown. The output lists graphemes, code points, categories and code point blocks found in your text, plus how many characters fall outside plain ASCII, giving you a full profile of what is actually in the string.
- 3. Cross-check unexpected entries. If a block or category looks out of place, such as a Cyrillic letter hiding inside Latin text, that is usually the sign of a copy-paste artifact or intentional lookalike character.
- 4. Copy the report. Copy the statistics into a bug report, code review comment or documentation note explaining exactly what characters a string contains and why.
When to use Analyze Unicode
Analyze Unicode turns a string into a statistics report covering grapheme count, code point count, Unicode categories and blocks, and the split between ASCII and non-ASCII content. Reach for it whenever you need to know exactly what a piece of text contains beyond what it looks like on screen.
- Debugging a length mismatch bug. A form field rejects a name because your backend counted UTF-16 units instead of graphemes. Running the string through the analyzer shows the gap between what a user sees and what the code measured.
- Auditing user-submitted usernames. Before allowing a display name into a leaderboard, you check its category breakdown to confirm it is not hiding control characters or an unexpected script mixed into a Latin name.
- Understanding an emoji sequence. A message like a family emoji is actually several code points joined with zero-width joiners. Analyzing it shows the true code point count versus the single grapheme a reader perceives.
- Documenting encoding edge cases. You are writing internal docs about how your system handles international text and want a concrete example showing code point blocks for a mixed Latin and CJK sample string.

About the Analyze Unicode tool
Analyze Unicode runs as plain JavaScript in your browser tab, with no server behind it. Print statistics about Unicode data and code points. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Unicode Tools section, 98 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Analyze Unicode free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
