Frequently asked questions
- What are zero-width characters?
- Unicode characters that take up no visible space: Zero-Width Space (U+200B), Zero-Width Non-Joiner (U+200C), Zero-Width Joiner (U+200D), and Zero-Width No-Break Space (U+FEFF). They are invisible but present in the text data.
- What is invisible watermarking?
- Inserting zero-width spaces between every character in a text. The text looks identical but contains a hidden pattern that can be detected later, useful for tracking copied content or identifying leak sources.
- Can zero-width characters cause problems?
- Yes. They can break string comparison, cause bugs in code, produce unexpected search results, and inflate character counts. Use the Detect and Remove modes to find and clean them from text.
