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.
