⟂ U+27C2 \perp, for example. This is a "show-stopper" for me.
Works ok for me on latex + windows:
\documentclass{article}
\usepackage{unicode-math}
\setmathfont{Cambria Math}
\begin{document}\pagestyle{empty}
$ ^^^^27c2 blblb $
\end{document}
(the document only uses cambria.ttc, so the glyph must be from this
font).
The context code
\setupbodyfont[cambria]
\starttext
$\perp $
abc
\stoptext
works fine for me too.
As Hans points out, \perp is U+22A5 (UP TACK), not U+27C2
(PERPENDICULAR), and might differ (in weight) from U+2225 (PARALLEL) or
\parallel, although this may depend on the particular font design.
(UP/DOWN/RIGHT/LEFT TACK are a set)
Is the definition used in char-ent.lua the right choice?
char-ent.lua:    ["perp"] = "⊥", -- U+022A5
Perhaps the latex package unicode-math makes the substitution for you.
(Note that dejavu has U+27C2.)
MWE:
\setupbodyfont [cambria,20pt]
%\setupbodyfont [dejavu,20pt]
\startTEXpage
$⊥⟂∥$
\stopTEXpage
its no big deal to have some backup btu i don't want to cycle through
