Invisible characters are Unicode code points that produce no visible output but can cause subtle bugs in code, break string comparisons, and even enable security attacks. Common examples include:
- Zero-Width Space (U+200B) — often copied from web pages and PDFs
- Zero-Width Joiner/Non-Joiner (U+200D/U+200C) — used in Arabic/Indic scripts and emoji sequences
- Byte Order Mark (U+FEFF) — appears at the start of UTF-8 files
- Soft Hyphen (U+00AD) — invisible line-break hint
- RTL/LTR Marks (U+200F/U+200E) — control text direction
Homoglyph attacks use characters from different scripts that look identical — for example, Cyrillic "а" (U+0430) looks exactly like Latin "a" (U+0061). Attackers use this to create deceptive URLs and usernames. This tool detects mixed-script text to help identify such attacks.
