From e7f3925bed86edf1b79fd18e5600252e445019d1 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 19 Nov 2021 09:06:36 -0800 Subject: [PATCH] Revert "grep/pcre2: fix an edge case concerning ascii patterns and UTF-8 data" This reverts commit ae39ba431ab861548eb60b4bd2e1d8b8813db76f, as it breaks "grep" when looking for a string in non UTF-8 haystack, when linked with certain versions of PCREv2 library.
