Subject: [PATCH v5] Emacs: Ensure left-to-right display for message headers
Date: Fri, 7 Aug 2020 07:46:41 +0300 [thread overview]
Message-ID: <20200807044641.3745-1-tlikonen@iki.fi> (raw)
In-Reply-To: <874kpfq14z.fsf@iki.fi>
In notmuch-show buffer insert invisible U+200E LEFT-TO-RIGHT MARK
character at the beginning of message header paragraph if the From
header contains a right-to-left character. This ensures that the
header paragraph is always rendered in left-to-right mode.
See Emacs Lisp reference manual section "(elisp) Bidirectional
Display" for more info.

As the commit description says this version inserts U+200E
LEFT-TO-RIGHT MARK only if the first header line (From header)
contains a right-to-left character.
This version is probably friendlier to the current test files which
don't expect to see U+200E LEFT-TO-RIGHT MARK in the output.
