Is there a TeX font containing Egyptological Alef and Ayn?

I am looking for a TeX font going smoothly with Computer Modern that contains the four characters Capital/Lowercase Egyptological Alef/Ayn (UNicode points U+A722...U+A725).

I have searched Scott Pakin's comprehensive LaTeX symbol list without success.

FreeSerif works, and comes with TeXLive:

\documentclass{standalone}
\usepackage{fontspec}
\begin{document}
The character {\fontspec{FreeSerif}Ꜣ} is quite strange
\end{document}


Typeset with XeLaTeX. This yields:

I found it by using FileFormat.info.

• .. and the FreeSerif interpretation of it is even more strange, I expected something like the "right half of digit 3" Jan 30 '18 at 13:30
• @jknappen I interpreted "going smoothly with Computer Modern" as "from a serif typeface", since CM has serifs (I suppose my ignorance in Egyptology is showing!). Going through the different interpretations of A722, it seems serif typefaces interpret it similarly to FreeSerif (two disconnected pieces with heavy terminals), whereas sans serif ones have one connected piece of constant weight, more like the "right half of digit 3".

• Going back to the sources: Here is the original proposal for the Egyptological characters to UNicode: std.dkuug.dk/JTC1/SC2/wg2/docs/n2241.pdf – "going smoothly with Computer Modern" basically means "being compatible in size and weight" Jan 30 '18 at 15:08
