Subject: bug#69718: 29.2; grep japanese-iso-8bit-unix string fails with "grep: illegal byte sequence"
Date: Wed, 13 Mar 2024 00:42:22 +0900 [thread overview]
Message-ID: <219184D7-3818-47AA-9722-BD4BCE85C0A0@gmail.com> (raw)
In-Reply-To: <86cys0vri9.fsf@gnu.org>
On japanese-iso-8bit-unix (= eucJP), この辞書は is 0xa4b3 0xa4ce 0xbcad 0xbdf1 0xa4cf,
and 0xa4b3 0xa4ce 0xbcad 0xbdf1 0xa4cf is illegal byte sequence on UTF-8.
On UTF-8 mode, macOS grep signals "grep: illegal byte sequence" error for the byte sequence,
but LANG=C mode or LANG is not specified, macOS grep accepts the byte sequence.

| grep: illegal byte sequence

emacs-29.1 executes /usr/bin/grep without LANG,
but emacs-29.2 seems to execute /usr/bin/grep with LANG=en_US.UTF-8.
I wonder /usr/bin/grep should be invoked in non UTF-8 mode, because emacs might pass non UTF-8 byte sequence to /usr/bin/grep.
