The following revision refers to this bug: https://chromium.googlesource.com/v8/v8.git/+/f918404590b6800c5a5ef26fb358abbc28622deb commit f918404590b6800c5a5ef26fb358abbc28622deb Author: littledan <littledan@chromium.org> Date: Thu May 04 12:33:38 2017 Revert of [regexp] Support unicode capture names in non-unicode patterns (patchset #3 id:40001 of https://codereview.chromium.org/2791163003/ ) Reason for revert: The decision for the specification was to not have this syntax, and instead the syntax before this patch. Original issue's description: > [regexp] Support unicode capture names in non-unicode patterns > > This ensures that capture names containing surrogate pairs are parsed > correctly even in non-unicode RegExp patterns by introducing a new > scanning mode which unconditionally combines surrogate pairs. > > BUG= v8:5437 , v8:6192 > > Review-Url: https://codereview.chromium.org/2791163003 > Cr-Commit-Position: refs/heads/master@{#44466} > Committed: https://chromium.googlesource.com/v8/v8/+/a8651c5671dd6e41595ffb438e7ea013082f2d38 R=yangguo@chromium.org,jgruber@chromium.org # Not skipping CQ checks because original CL landed more than 1 days ago.
