Frequently asked questions

Everything you need to know about using invisible characters.

Invisible characters are Unicode code points that render no visible glyph but still occupy space or affect text behavior. They are commonly inserted by social platforms, word processors, PDF exports, and copy-paste operations. Common examples include zero-width spaces (U+200B), Hangul fillers (U+3164), and byte-order marks (U+FEFF).
