DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.223

Broader invisible-character detection in text sanitisation

You'll notice
Useful3 Signal0
Text Sanitization

More kinds of hidden and invisible characters are now stripped out of text you paste or read.

What

The sanitisation regex now catches more classes of hidden characters in text.

Details
  • previously matched only default-ignorable code points
  • now also matches control, format, private-use and unassigned categories, plus line and paragraph separators and backslash
Evidence

\p{Default_Ignorable_Code_Point}

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
