​I have had trouble processing text with diacritical marks using the more
recent betas and the Brill font.​ Some of this can be remedied by
re-entering the diacritical marks in the source file. (This works very well
with Greek.) But there remain some problem passages.

Consider:

\definefontfamily[mainface][serif][Brill] %[TeX Gyre Termes]

\setupbodyfont[mainface,10pt]


\starttext
ı̓tn und ı̓tn.t               %Line 1
Altägyptischen            %Line 2
\stoptext

Note:
(a) there is no problem at all with other fonts, e.g., Tex Gyre Termes
(b) with the Brill font, the text fails to process when BOTH Line1 and 2
are included.

The console readout is:

tex error       > tex error on line 1 in file
/Users/bowen1/Desktop/TestTeX/fonttest.tex: ?

             \dosingleempty \page_breaks_process

\strc_pagenumbers_flush_final_page ...\else \page

                                                  [\p_strc_pagenumbers_page

\dostoptext ...\strc_pagenumbers_flush_final_page

                                                  \page \the \everystoptext

I have no idea where the problem here lies, whether it is with ConTEXt or
with the Brill font. So, while a fix would be ideal, a diagnosis that I
could relay to Brill would be good too.
