Invisible Character Checker
Detect Unicode Tags, Variation Selectors, and zero-width characters that exist as actual code points in a URL or file. Separated zero-width sequences are recombined before decoding. Elements hidden with CSS or JavaScript are outside the scope of this checker.
What is checked
- Unicode Tags Block (U+E0000–U+E007F)
- Variation Selectors (U+FE00–U+FE0F and U+E0100–U+E01EF)
- Binary text encoded with zero-width characters, including segments separated by visible characters
The checker does not classify detected characters as normal or abnormal and does not issue warnings. It displays their code points and text decoded in stages with known UTF-8, UTF-16BE, and Base64 mappings.
