Invisible Character & Zero-Width Space Detector
Find hidden formatting breaking your code. This tool detects zero-width spaces, non-breaking spaces, and hidden Unicode characters that cause syntax errors in programming and databases.
Debugging Hidden Characters
When copying text from PDFs, Slack, or Word documents, invisible Unicode characters (like U+200B Zero-Width Space) often tag along. These characters are invisible to the naked eye but will cause catastrophic syntax errors in code or database queries. This detector scans your string and visually highlights every hidden character, allowing you to strip them out instantly.

Frequently Asked Questions
A zero-width space (U+200B) is a non-printing character used in computerized typesetting to indicate word boundaries to text-processing systems, without displaying a visible space.
If you copied code from a blog or PDF, it likely contains hidden formatting characters or non-breaking spaces (U+00A0) that compilers and interpreters cannot parse.
