RandoziUnicode Inspector
Text that looks identical can hide a zero-width space, a non-breaking space or a character that reverses the reading order. Paste it and see every character, its code, how many bytes it takes and which ones are invisible.

How it works
- Paste or type the text you want to look at.
- Read the totals: characters, visible symbols, UTF-16 units and UTF-8 bytes.
- Check the table for flagged rows: invisible, space-like or direction-changing characters.
- Copy the code points if you need them for a bug report or a regular expression.
What people use it for
A value that “looks the same” but does not match
Find the non-breaking space or zero-width character that stops a copied word from matching.
Counting bytes

Checking an emoji
See how one family emoji is five code points joined by invisible connectors.
Questions
- What is the difference between the counts?
- Code points are the characters of the Unicode standard (é is one). UTF-16 units are what JavaScript counts as length: an emoji takes two. UTF-8 bytes are what is stored in most files and sent over the web: é takes two, an emoji four. Symbols (graphemes) are what a reader sees as one character: a family emoji is one symbol made of five code points.
- Which characters are flagged?
- Zero-width spaces and joiners, the byte order mark, non-breaking and other special spaces, soft hyphens, direction marks and controls that can reorder text, variation selectors, control characters, private-use characters, lone surrogates and the replacement character. Line feeds and tabs are listed but not counted as problems. The list is a reading aid, not a security scanner.
- Why are there no character names?
- A table of names for every character is a large database and would slow the page down. The code, for example U+00E9, is enough to look a character up in any Unicode chart.
- How much text is read?
- The totals count the whole text, up to 300,000 characters. The table shows the first 2,000 characters. Nothing is sent or stored.
