These were not typos.
The manual continues to contain non-ascii characters, and has done for
over 7 years, ref eg 681ebc3315. Eg there are several i-acute in ack.texi.
They all seem to display fine in eg

Sebastian seems to say that is not the case?

The original problem report was about the Texinfo input “Bahá'í” (with U+0027
APOSTROPHE), which Texinfo renders as “Bahá’í” (with U+2019 RIGHT SINGLE
QUOTATION MARK) in info and as something similar-looking in TeX.

The quick patch was to change the Texinfo input to “Bah@'{a}@t{'}@'{i}”; the @'
calls were to suppress false-alarm diagnostics and I don't know why the @t{'}
was put in.

It now appears that there's no need to worry about the false-alarm diagnostics
(the output is fine, as Glenn noted). Also, the @t{'} is not necessary in that
it puts one wrong character into the output (namely, U+0027) instead of a
different wrong character (namely, U+2019).

The preferred Unicode spelling these days is “Baháʼí” (with U+02BC MODIFIED
LETTER APOSTROPHE). However, although Texinfo can handle that character and puts
it into info files, the character doesn’t survive transliteration to TeX (it
gets lost). I don't know whether this is a bug in Texinfo or in TeX, but anyway
we need to work around it if we're going to use the correct spelling.

I suggest that we use the preferred spelling in info files, and fall back on the
previous behavior of using apostrophe (which TeX renders like the right single
quotation mark) when outputting to TeX. I’m attaching a proposed patch, which I
emailed to Eli earlier before seeing this bug report. This patch also fixes
other instances of similar problems that I found.

Use better accents for Baháʼí wordsm in diagnostics etc.
Some problems still remain.  For example, because Emacs renders
the digraph “s͟h” in “Mas͟híyyat” almost as if it were “s_h” instead
of underlining the “s” and “h” as it should, just spell it
“Mashíyyat” for now.

When I put this "modified letter apostrophe" alone in calendar.texi
and build PDF, in emacs.log the following line appear: "Unicode char
@u8:ʼ not defined for Texinfo", so perhaps it is Texinfo that
"mishandles" the apostrophe, not TeX.

Look for \DeclareUnicodeCharacter in texinfo.tex to see the list of
Unicode characters that are supported.

When using XeTeX or LuaTeX, texinfo uses their native UTF-8 support,
which means all characters are supported.

Looks like in TEXINFO.TEX v2020-05-08.18 there is no
"DeclareUnicodeCharacter" for this character, but I guess it shouldn't
be that difficult to add it.  Maybe we could request it?

The @t{} trick was to avoid converting ' into ’, which is definitely
not how this word should be displayed.  So I think the @iftex part of
your proposal needs to use @t{'}.

Is that official?  Can you tell where you saw that this is the
preferred spelling?  We should be very careful with such situations,
as people tend to get offended when their names or the names of their
nation or religion or language is misspelled.

Thanks.

bahai.org disagrees; see below.

I got it from Wikipedia. :-)

I looked into it more. There’s nothing official as far as Bahá’í and Unicode
goes, as far as I could find.

The Bahá’í main website bahai.org spells it “Bahá’í” (with U+2019 RIGHT SINGLE
QUOTATION MARK). Its style guide complains, “Bahá’í, Bahá’u’lláh, and other
names are written with accent marks, but many publications and Web sites do not
have the facility for using such marks.”[1] without saying whether the accent
marks used on its own website are correct or have been bowdlerized in order to
cater to browsers lacking U+02BC MODIFIER LETTER APOSTROPHE. Certainly bahai.org
is doing bowdlerization; for example, their calendar page[2] uses
‘<u>Sh</u>araf’ to display “S͟haraf”, even though Unicode says it should instead
use U+035F COMBINING DOUBLE MACRON BELOW between the “S” and the “h”; here the
web page is understandably bowdlerizing because too many browsers (Emacs
included) don't render the Unicode “S͟haraf” well.

Getting back to the hamzah (the apostrophe-like character in question), here’s
how other sources represent it in Latin transliterations:

  ' U+0027 - ArabTeX (presumably because it displays as U+2019 in TeX)
  ʼ U+02BC - Library of Congress, various geographic names standards
             (UN, US, UK), Hans Wehr
  ʾ U+02BE - Deutsches Institut für Normung, Encyclopaedia of Islam
  ˈ U+02C8 - ISO

Presumably English Wikipedia uses U+02BC because of UN/US/UK/LoC. That being
said, bahai.org is as definitive as it gets on the web for Bahá’ís; if that
website uses U+2019 to represent hamzah, we’re in good company and can mostly
stick with what we’ve got.

Proposed patch attached.
