Unicode Character Inspector

Paste any string and see every character broken down — codepoint, UTF-16 unit, UTF-8 bytes, name, category, and HTML entity. Detect invisible characters, zero-width spaces, BOMs, and homoglyphs that can break code or fool users. Supports emoji, combining marks, and surrogate pairs.

Why choose Unicode Character Inspector?

The Unicode Character Inspector allows you to paste any string and immediately break down every character by its codepoint, UTF-16 unit, UTF-8 bytes, name, category, and HTML entity. It helps you quickly detect invisible characters, zero-width spaces, BOMs, and homoglyphs that can disrupt code or obscure text. Completely free and accessible directly in the browser, it requires no installation or account setup.

Good to know: Very large blocks of text or automated batch processing may require programmatic libraries rather than a browser-based inspection tool.
