Unicode Mixed Script Detector

Detect mixed Unicode scripts online

This Unicode script detector inspects every code point, identifies Latin, Cyrillic, Greek, Arabic, Hebrew, Han and other scripts from bundled Unicode Script data, reports all scripts, separates substantive scripts from Common and Inherited, shows per-character details, reports script transitions, optionally reports a dominant substantive script, preserves the original text and runs locally in the browser.

Mixed-script example

The default example раypal.com starts with Cyrillic U+0440 CYRILLIC SMALL LETTER ER and U+0430 CYRILLIC SMALL LETTER A, then switches to Latin letters. The full stop is Common.

Expected summary: all scripts are Cyrillic, Latin and Common; substantive scripts are Cyrillic and Latin; mixed substantive scripts are reported as yes; dominant substantive script is Latin; and the substantive transition is Cyrillic → Latin at position 3.

How Unicode scripts are identified

Unicode assigns Script properties to code points. Many letters belong to a specific script, while punctuation and digits often use Common, and combining marks often use Inherited. Script detection identifies writing systems, not language; the same script can be used by many languages. This page uses bundled Unicode Script data version 17.0.0. Script Extensions data is not bundled, so shared-script edge cases are reported by primary Script only.

Common and inherited characters

Common includes many digits, punctuation marks, symbols, emoji and spaces. Inherited often includes combining marks that inherit surrounding script context. These properties are reported separately, but they do not independently create a mixed substantive-script warning. For example, abc-123.com contains Latin and Common, while decomposed é contains Latin and Inherited.

Script transitions and dominant scripts

A transition occurs when substantive writing systems change. Common punctuation between scripts is skipped when looking for substantive transitions, so abc-абв reports a Latin-to-Cyrillic transition at the Cyrillic letter, not at the hyphen. A dominant script is the most frequent substantive script; ties produce no single dominant script. Dominance does not prove intent.

Mixed scripts vs confusable characters

Mixed-script detection identifies multiple writing systems. Confusable detection identifies visually similar characters or sequences. A mixed-script string may contain no confusables, and a same-script string may still contain confusables. This tool does not attempt full confusable mapping.

To inspect Unicode lookalikes, homoglyphs and confusable skeletons, use the Confusable Character Detector.

Legitimate multilingual text

Mixed scripts are common in translations, names, citations, technical text, brand names and international content. The result is a review signal, not proof of spoofing or abuse.

How to use the detector

1. Paste or type Unicode text into the input field.
2. Run the script analysis.
3. Review all detected scripts and substantive scripts.
4. Inspect character details and script transitions.
5. Use the Confusable Character Detector when visual lookalikes also need review.
6. Copy or download the script report if needed.

Common use cases

• Detect Cyrillic characters in mostly Latin text.
• Inspect multilingual strings and imported content.
• Review domain-like strings for mixed writing systems.
• Debug identifiers that contain unexpected scripts.
• Analyze filenames, usernames and product names.
• Inspect script transitions in user-generated content.
• Create Unicode security test fixtures.
• Separate script analysis from confusable-character analysis.
