​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

                                                  [\p_strc_pagenumbers_page ...

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

 3     

 4     \setupbodyfont[mainface,10pt]

 5     

 6     

 7     \starttext

 8     ı̓tn und ı̓tn.t 

 9     Altägyptischen 

10     \stoptext

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.
