Trouble in biber with "ḥʼḤ"

Question

I am facing issues with special characters in biber. Specifically, this is about "ʼ", "ḥ" and "Ḥ". These are used for Arabic transcription.
I have tried rendering this with LuaLaTeX instead of PDFLaTeX, this solved the issue insofar as it renders the document, but the "ʼ" is replaced by a rectangle in the document.
I have also tried adding bibencoding = ascii and texencoding = ascii. Both resulted in the document not rendering.

I have also looked at this question and this question. They are related, but don't offer a working soloution.
Furthermore, my ref.bib file is created by Zotero, so I would much prefer not having to change its contents.

You can help LaTeX and provide the representation of the unknown characters.

How do you get the codes? Look in the log file when you get the error!

! Package inputenc Error: Unicode character ʼ (U+02BC)
(inputenc)                not set up for use with LaTeX.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
 ...

Alternatively, do

usepackage{newunicodechar}

newunicodechar{ʼ}{'}
newunicodechar{Ḥ}{d{H}} % d is dot under accent
newunicodechar{ḥ}{d{h}}
