Language Identifier
Identify Unicode writing scripts, character sets, and language candidates locally with deterministic pattern scoring and mixed-script detection.
Unicode Writing Script & Language Detection Utility
Internationalization and multilingual text processing require accurate identification of underlying writing systems, character block encodings, and natural language properties.
This tool provides client-side Unicode script classification and language candidate scoring. It evaluates character frequency across major world alphabets (Latin, Cyrillic, Devanagari, Han, Arabic, Japanese Kana, Greek, Hebrew, and more), detects mixed-script compositions, and matches vocabulary features.
Core Tool Capabilities
- Unicode Script Detection: Categorizes characters across 15+ world writing scripts with exact percentage distribution bars.
- Language Candidate Scoring: Identifies primary language candidates with confidence levels based on characteristic n-grams and stop words.
- Mixed-Script Analysis: Detects bilingual or code-switched text with sample character breakdowns per writing system.
- Character Composition Metrics: Precise breakdown of letters, numeric digits, punctuation, whitespace, and symbols.

Frequently Asked Questions
- How does the tool identify scripts?
- The engine matches characters against Unicode property escape blocks (e.g. \p{Script=Devanagari}, \p{Script=Cyrillic}, \p{Script=Han}) to calculate exact script frequencies.
- Can it detect text written in multiple languages or scripts?
- Yes. If your text mixes different scripts (e.g. English Latin and Hindi Devanagari), the tool flags it as Mixed Scripts and displays the proportional percentage of each script.
- Is short text supported?
- Script detection is accurate even on single characters. Natural language candidate scoring achieves high confidence on samples of 10+ words.
- Is any data uploaded to cloud servers?
- No. All Unicode analysis is executed locally inside your web browser.
