Unicode Inspector

Key features

• Code-point accurate analysis (surrogate-pair safe): counts characters, UTF-8 bytes, grapheme clusters and lines, even for emoji and ZWJ sequences.
• A character map shows the first 200 code points with U+ notation, decimal value, UTF-8 hex bytes and known names.
• Invisible-character radar flags zero-width spaces, joiners, BOMs, bidirectional marks, soft hyphens and unusual separators with counts and positions.
• Four escape representations at once: \uXXXX, \u{…}, HTML numeric entities and percent-encoded UTF-8 — each individually copyable.
• A decoder accepts mixed \u, &#x…;, &#…; and %XX input and reconstructs the original text, with malformed sequences reported instead of crashing.

How it works

1. 1

   Paste the suspicious text

   A broken URL, a weird-looking name, a copy-pasted password — anything. Stats appear live a third of a second after you stop typing.

2. 2

   Read the map and the warnings

   The character table shows every code point; the radar panel lists any invisible or control characters found, where they are, and how many.

3. 3

   Escape, decode, or clean up

   Copy any escape representation for use in code, or paste escaped text into the decoder to see what it really says.

Tips for better results

• 💡“Why does this URL 404?” often means a zero-width space rode along from a chat app paste — the radar panel names it in seconds.
• 💡Grapheme clusters (what humans read as one character) can contain many code points — a family emoji is 7 of them; both counts are shown so nothing surprises you.
• 💡Strip invisible characters by combining this tool's findings with the Case Converter's whitespace cleanup, then re-inspect to confirm a clean report.
