[PATCH v2 00/40] Use ASCII subset instead of UTF-8 alternate symbols

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

This series contain basically a cleanup from all those years of converting
files to ReST.

During the conversion period, several tools like LaTeX, pandoc, DocBook
and some specially-written scripts were used in order to convert
existing documents.

Such conversion tools - plus some text editor like LibreOffice  or similar  - have
a set of rules that turns some typed ASCII characters into UTF-8 alternatives,
for instance converting commas into curly commas and adding non-breakable
spaces. All of those are meant to produce better results when the text is
displayed in HTML or PDF formats.

While it is perfectly fine to use UTF-8 characters in Linux, and specially at
the documentation,  it is better to  stick to the ASCII subset  on such
particular case,  due to a couple of reasons:

1. it makes life easier for tools like grep;
2. they easier to edit with the some commonly used text/source
   code editors.
    
Also, Sphinx already do such conversion automatically outside 
literal blocks, as described at:

       https://docutils.sourceforge.io/docs/user/smartquotes.html

In this series, the following UTF-8 symbols are replaced:

            - U+00a0 (' '): NO-BREAK SPACE
            - U+00ad ('­'): SOFT HYPHEN
            - U+00b4 ('´'): ACUTE ACCENT
            - U+00d7 ('×'): MULTIPLICATION SIGN
            - U+2010 ('‐'): HYPHEN
            - U+2018 ('‘'): LEFT SINGLE QUOTATION MARK
            - U+2019 ('’'): RIGHT SINGLE QUOTATION MARK
            - U+201c ('“'): LEFT DOUBLE QUOTATION MARK
            - U+201d ('”'): RIGHT DOUBLE QUOTATION MARK
            - U+2212 ('−'): MINUS SIGN
            - U+2217 ('∗'): ASTERISK OPERATOR
            - U+feff (''): ZERO WIDTH NO-BREAK SPACE (BOM)

---

v2:
- removed EM/EN DASH conversion from this patchset;
- removed a few fixes, as those were addressed on a separate series.
 
PS.:
   The first version of this series was posted with a different name:

	https://lore.kernel.org/lkml/cover.1620641727.git.mchehab+huawei@kernel.org/

   I also changed the patch texts, in order to better describe the patches goals.
