There are several UTF-8 characters at the Kernel's documentation.
Several of them were due to the process of converting files from
DocBook, LaTeX, HTML and Markdown. They were probably introduced
by the conversion tools used on that time.
Other UTF-8 characters were added along the time, but they're easily
replaceable by ASCII chars.
As Linux developers are all around the globe, and not everybody has UTF-8
as their default charset, better to use UTF-8 only on cases where it is really
needed.
The first 3 patches on this series were manually written, in order to solve
a few special cases.
The remaining patches on series address such cases on *.rst files and
inside the Documentation/ABI, using this perl map table in order to do the
charset conversion:
my %char_map = (
0x2010 => '-', # HYPHEN
0xad => '-', # SOFT HYPHEN
0x2013 => '-', # EN DASH
0x2014 => '-', # EM DASH
0x2018 => "'", # LEFT SINGLE QUOTATION MARK
0x2019 => "'", # RIGHT SINGLE QUOTATION MARK
0xb4 => "'", # ACUTE ACCENT
0x201c => '"', # LEFT DOUBLE QUOTATION MARK
0x201d => '"', # RIGHT DOUBLE QUOTATION MARK
0x2212 => '-', # MINUS SIGN
0x2217 => '*', # ASTERISK OPERATOR
0xd7 => 'x', # MULTIPLICATION SIGN
0xbb => '>', # RIGHT-POINTING DOUBLE ANGLE QUOTATION MARK
0xa0 => ' ', # NO-BREAK SPACE
0xfeff => '', # ZERO WIDTH NO-BREAK SPACE
);
After the conversion, those UTF-8 chars will be kept:
- U+00a9 ('©'): COPYRIGHT SIGN
- U+00ac ('¬'): NOT SIGN # only at Documentation/powerpc/transactional_memory.rst
- U+00ae ('®'): REGISTERED SIGN

PS.: maintainers were bcc on patch 00/53, in order to reduce the
risk of patch 00 to be rejected by list servers.

For U+00b7 ('·'): MIDDLE DOT, I opted to keep it on a few places:
- Documentation/devicetree/bindings/clock/qcom,rpmcc.txt
As this file will be some day converted to yaml, where the
MIDDLE DOT will be removed, I guess it is not worth touching it.
- Documentation/scheduler/sched-deadline.rst
There, it is used on a math expressions. So, better to keep.
- Documentation/devicetree/bindings/media/video-interface-devices.yaml
There, it part of an ASCII artwork.
- translations/zh_CN
I prefer not touching it, as it might have some special meaning in Simplified Chinese.
