Inspect every code point in a string: hex, decimal, UTF-8 byte sequence, Unicode category, and visual form. Useful for debugging text encoding issues, finding invisible characters (zero-width space, BOM), or comparing visually-similar characters (Cyrillic а vs Latin a).
How to use the Unicode Inspector
Paste text. Every code point shows on its own row with hex code, decimal, glyph, UTF-8 byte sequence, and category. The summary at top gives character count, code-point count, and UTF-8 byte size — these can differ for strings with multi-code-point characters (like emoji with skin-tone modifiers).
About code points, characters, and bytes
One "character" you see is often multiple code points, which is often multiple UTF-8 bytes. The emoji "👨👩👧" looks like one glyph but is 8 code points joined by zero-width joiners — and 25 UTF-8 bytes. String.length in JavaScript counts UTF-16 code units, not code points or characters, which is why '👋'.length === 2.
This tool helps debug when those numbers diverge in unexpected ways — for example, when a database column with a length limit silently truncates emoji, or when a tokenizer splits a character in a surprising place.
Frequently asked questions
What does it show for each character?
The code point in hex and decimal, the Unicode name, block and category, the UTF-8 byte sequence and the visual glyph.
Can it find invisible characters?
Yes. It surfaces zero-width spaces, byte-order marks and other invisible or control characters that break text comparisons and parsing.
How do I spot look-alike characters?
Inspect the code points: visually identical glyphs like Latin "a" and Cyrillic "a" have different code points, which the inspector shows side by side.
