To convert from XeLaTeX source to
.docx, I am using the solution provided by Michal Hoftich. (See there for MWE and the solution by @michal.h21.)
That setup works great for converting Unicode, but I noticed that it gobbles up the Greek Unicode character ἀ. That is,
ἀ in the source yields nothing in the output.
Is there a simple way to fix that bug?
