Count Chinese Han characters, Chinese punctuation, unique Han characters, and Simplified or Traditional signals in multilingual text, translations, and copied content.
Chinese Character Counter converts raw pasted text into a clear analytics report. It shows the main count, supporting metrics, density, and an interpretation that helps you decide whether the text needs cleanup or review.
All processing happens locally in the browser. No server upload is required for pasted text.
Example input: This text mixes Chinese: 这是中文内容。繁體中文也可以檢查。Numbers 123 and symbols # are ignored.
Chinese Character Counter uses deterministic character matching and script-aware checks where applicable. It also calculates total characters, lines, density, frequency, and category-specific quality signals.
Language detection is heuristic, not a full linguistic classifier. For legal, academic, or production validation, review the exported report manually.

It estimates simplified, traditional, or mixed usage based on common character markers.
