High-signal invisible Unicode characters we clean
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.

Definition
A Dedicated Paste Clean Workflow for Spotless Copy
01
When moving text between AI assistants, web browsers, and collaborative documents, invisible formatting artifacts often tag along. These rogue code points cause unpredictable line breaks, broken hyperlinks, and visual misalignment.
02
Clean Paste AI establishes a dependable paste-clean workflow. Before pasting copied text into your final documents, run it through our private browser utility to purge all hidden Unicode clutter in milliseconds.
03
Our local scanner checks against 60+ invisible characters, giving you an exact inventory of what was removed so you can be confident in your text hygiene.
04
For drafts that also need stylistic improvements, our Pro reconstruction pipeline provides meaning-preserving rewrites.
Technical Sources
How the Three AI Output Traces Differ
Invisible Unicode artifacts, Markdown residue, and official statistical watermarks are three distinct mechanisms with different solutions.
| Mechanism | Technical Description | How Clean Paste AI Handles It |
|---|---|---|
| Invisible Unicode Artifacts | Zero-width spaces (U+200B), narrow no-break spaces (U+202F), and format code points copied from web UIs. | Free local in-browser scan and deletion. Visible words remain unchanged. |
| Markdown & Formatting Noise | Heading hashes, bold asterisks, code fences, and bracketed links. | Free local in-browser stripping to clean plain text. |
| Statistical Sampling Watermarks | Mathematical bias in token selection probability during model generation (e.g., Claude's official watermark). | Pro semantic sentence reconstruction. Rebuilds phrasing while keeping meaning intact. |
“Nothing is added to the text and there are no hidden characters.”
“U+200B ZERO WIDTH SPACE is intended for line break control without displaying a visible space.”
Markdown syntax adheres to the CommonMark specification: CommonMark Specification.
