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.

What
Smart-quote normalization recognizes more double-quote lookalikes, including the ornamental and heavy quote characters, and now matches runs of two or more apostrophe lookalikes.
Details
Added characters include U+2E42, U+02F5/U+02F6, U+2034 and U+2037, U+2760 and the U+1F676 to U+1F678 ornaments.
The character class is now matched with a Unicode-aware regex.
