Does Claude Text Cleaner Remove Em Dashes Without Replacing Them?

Yes. This browser-only cleaner deletes U+2014 EM DASH. It does not insert a space, comma, hyphen, or other replacement. If an em dash joins two unspaced words, the cleaned result can run them together. Save the original and review the sentence before copying the result.

What the live report shows

In a live browser check on October 18, pasting Wait—please produced Waitplease. The report showed original length 11, clean length 10, removed characters 1, changed categories 1, and “Em dash” 1. The cleaner counts Unicode code points in the pasted text. This example has no spaces around the dash, so deleting it makes the adjacent words meet.

U+2014 is the exact character this category matches. In the same live check, Wait–please with U+2013 EN DASH stayed unchanged, with zero removals. A zero count for that example means this cleaner did not match a supported removal character; it is not an assessment of the writing or its origin.

How to keep the sentence readable

  1. Keep the original. Clean a copy so the intended punctuation remains available.
  2. Read the report. An “Em dash” count above zero tells you how many U+2014 characters were deleted, though the report does not mark their positions.
  3. Compare sentences. Look for joined words or a lost break. Add a space or punctuation yourself where the sentence needs it, or keep the original dash when it is intentional.
  4. Check the destination. Read the final text in the editor or publishing system where it will appear.

A public question about spacing around em dashes shows why surrounding spaces are an editorial choice. A writer's question about removing em dashes raises the related decision of whether to remove them at all. Neither question establishes that em dashes are a watermark or that any particular text came from Claude.

This site's cleaner makes a literal character change; it does not rewrite sentences, identify AI authorship, or predict any detector result. For the full supported-character list, see how to read the cleaning report. For another case where a removed code point can matter, see joined emoji.
