=C2=A0 =C2=A0 Interestingly the table of contents looks fine if I put the n= umber
=C2=A0 =C2=A0 inside an LTR macro; still in the main body, the section head= s are
=C2=A0 =C2=A0 typeset incorrectly.

=C2=A0 =C2=A0 I guess the solution is to get the entire section head number= string
=C2=A0 =C2=A0 (e.g., 1.10) to have RTL direction, however, each individual = number
=C2=A0 =C2=A0 string inside (say, 1 or 10) should be written LTR.=C2=A0 How= can this be
=C2=A0 =C2=A0 achieved?

=C2=A0 =C2=A0 The six TeX files (with corresponding PDF outputs) are attach= ed.

=C2=A0 =C2=A0 BTW this is using ConTeXt ver: 2016.04.01 13:01 MKIV beta f= mt:
=C2=A0 =C2=A0 2016.4.7 int: english/english, running LuaTeX, Version beta-0= .90.0
