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.

Escaped backticks unescape correctly in template-literal strings

You'll notice

Internals

Fixes escaped backticks being dropped when parsing template-literal strings.

What

The unescape routine for template-literal-style strings handles an escaped backtick instead of dropping it through the generic character branch.

Details
  • Rewritten as a single pass with an explicit escaped-backtick case.
  • The line-continuation strip is folded into the same regex.
Evidence

\uFFFD

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