These code points appear most frequently in AI chat pastes and document exports. The full scan covers 60 characters; here are the common offenders.
| Code | Character Name | Why it breaks pastes |
|---|---|---|
| U+200B | Zero Width Space | Invisible separator; breaks word counts, search and URLs. Common AI/copy artifact. |
| U+200C | Zero Width Non-Joiner | Invisible; controls ligature joining. Often unintended residue. |
| U+200D | Zero Width Joiner | Invisible; joins glyphs/emoji. Can be watermark residue in plain text. |
| U+FEFF | Zero Width No-Break Space (BOM) | Byte order mark / invisible; corrupts leading text and parsing. |
| U+00A0 | No-Break Space | Looks like a space but blocks line breaks; breaks search matching. |
| U+202F | Narrow No-Break Space (NNBSP) | The main 'ChatGPT o3/o4-mini' artifact. Looks like a space, different code point. |
| U+00AD | Soft Hyphen | Invisible unless line wraps; splits words for search. |
| U+202E | Right-To-Left Override | Bidi override; strong spoofing risk. |
Our in-browser scanner checks the full catalog of 60 invisible code points, including directional controls and zero-width joiners.

Text Hygiene Concept
Clean AI Text for Publishing: Why Blog Posts Need a Character Pass
01
Copying drafted articles from automated assistants into blogging platforms often carries hidden prompt artifacts. Web chat windows insert soft hyphens, zero-width tags, and non-breaking spaces that distort font rendering on live web pages.
02
These rogue characters cause unsightly typographical glitches, such as isolated words floating on new lines or broken headline links. Search engine crawlers can also index these invisible tokens, affecting structured data parsers.
03
AI Text Cleaner eliminates these problems with an instant client-side scan. It isolates and removes 60+ known non-printing Unicode codepoints while standardizing spacing according to Unicode NFC rules.
04
Your final blog draft emerges clean, normalized, and visually harmonious across desktop screens, tablets, and smartphones.
