Unicode Inspector ★

What is Unicode Inspector?

The Unicode inspector breaks any text down character by character and highlights the ones that tend to cause hard-to-detect bugs: zero-width spaces (U+200B), byte order marks (BOM), non-breaking spaces and homoglyphs — letters from other alphabets that look Latin, like the Cyrillic "А" that looks identical to "A".

These invisible characters are a classic source of errors: passwords that "don't match", identifiers that fail to compare, or strings copied from the web that break your code for no apparent reason. Paste the suspicious text and you'll see exactly what it contains and where the problem is. All analysis happens locally in your browser.
