Does Claude Text Cleaner Change Subdivision Flag Emoji?

Yes. A Scotland flag sequence loses its subdivision identity when this browser cleaner removes its six invisible tag code points. The seven-code-point input becomes U+1F3F4 BLACK FLAG alone. The live report shows original length 7, clean length 1, removed characters 6, changed categories 1, and “Tag characters” 6. Save the original if the flag matters; the visible glyph depends on the app and font.

Code-point labels make the invisible change clear even where the flag glyph is unsupported. This diagram describes stored text, not a promised appearance on every device.

What the live cleaner does

Unicode Emoji, Annex C lists the Scotland flag as BLACK FLAG followed by tag letters for gbsct and a cancel tag. This site's browser script removes code points in U+E0000–U+E007F, including those six tags, while retaining U+1F3F4. In a live browser test, the complete sequence 🏴󠁧󠁢󠁳󠁣󠁴󠁿 became 🏴. The count is based on Unicode code points, not displayed emoji glyphs.

The report totals matched removals. It cannot tell whether a tag was accidental or whether a document needs it. Unicode also explains that display support for valid tag sequences varies, so compare the underlying sequence and check the result in the destination app.

How to preserve a flag that matters

  1. Keep a copy of the original before cleaning. If you paste the example above, copy the whole code span; its five tag letters and cancel tag are invisible.
  2. Run the cleaner and inspect the “Tag characters” count. Six removals in this example mean the subdivision sequence no longer survives intact.
  3. For a flag, identifier, or archived text that must stay exact, restore the original sequence and verify it in the destination editor.

Public Unicode questions ask whether the Scotland sequence behaves as one grapheme and what Unicode tags can represent. Neither question establishes that the text came from Claude. For other emoji changes, see the joiner and variation-selector guide. This tool only cleans pasted text locally; it does not identify a watermark or assess authorship.
