Subject: [PATCH v2 06/40] docs: trace: coresight: coresight-etm4x-reference.rst: Use ASCII subset instead of UTF-8 alternate symbols
Date: Wed, 12 May 2021 14:50:10 +0200	[thread overview]
Message-ID: <14c34b8034d4916c5f81c59b6c7f28d622a84bb4.1620823573.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1620823573.git.mchehab+huawei@kernel.org>

The conversion tools used during DocBook/LaTeX/Markdown->ReST conversion
and some automatic rules which exists on certain text editors like
LibreOffice turned ASCII characters into some UTF-8 alternatives that
are better displayed on html and PDF.

While it is OK to use UTF-8 characters in Linux, it is better to
use the ASCII subset instead of using an UTF-8 equivalent character
as it makes life easier for tools like grep, and are easier to edit
with the some commonly used text/source code editors.

Also, Sphinx already do such conversion automatically outside literal blocks:
   https://docutils.sourceforge.io/docs/user/smartquotes.html

So, replace the occurences of the following UTF-8 characters:

	- U+00a0 (' '): NO-BREAK SPACE
	- U+2018 ('‘'): LEFT SINGLE QUOTATION MARK
	- U+2019 ('’'): RIGHT SINGLE QUOTATION MARK
