It is a long time now that NewComputerModern has build-in
information for diacritics stacking.<br>
I have heard that xetex supports this but I can not make it work.
The font is developed <br>
with fontforge and as you can see in the attached screenshot,
fontforge shows stacking working.<br>
<br>
However xelatex just places, say the grave (uni0300) next and not
above the character, say uni2C9B<br>
(as in screenshot).<br>
<br>
So I guess I have something wrong in the font that xetex does not
like(?)<br>
<br>
The font currently develops the coptic block for academic needs this
is why I use uni2C9B.<br>
<br>
A sample file is<br>
<br>
\documentclass{article}<br>
\usepackage{fontspec}<br>
\setmainfont{NewCM10-Regular.otf}<br>
\begin{document}<br>
ⲛ̀<br>
\end{document}<br>
<br>
However the font that contains this character (since it is under
development) is here:<br>
<a moz-do-not-send="true"
href="https://myria.math.aegean.gr/~atsol/tmp/NewCM10-Regular.sfd">https://myria.math.aegean.gr/~atsol/tmp/NewCM10-Regular.sfd</a><br>
<a moz-do-not-send="true"
href="https://myria.math.aegean.gr/~atsol/tmp/NewCM10-Regular.otf">https://myria.math.aegean.gr/~atsol/tmp/NewCM10-Regular.otf</a><br>

thanks for any help,<br>
