An obscure unicode error, minimal example:
\starttext
(≡) should be ($\equiv$)
\stoptext

Well, this works: $≡$
(This is not to say that the character ≡ alone should not work, but it
may be that it is simply missing in the text font and no mechanism is
there that would switch to "math mode".)

The character "≡" in text can be find in some CJK fonts. For example:
\definefont[song][name:adobesongstdlight]
\starttext
\song
(≡) should be ($\equiv$)
\stoptext

indeed. of course one could use the math font as base font as well, but
that would complicate matters a bit as we use a virtual font (so instead
of the default set one would need to specify multiple featuresets, which
actually is supported)
another solution is do define fallbacks but I have no time right now to
do that (it would slow down loading a bit); some time in the future we
will have the option in luatex to add missing glyphs to a font using a
'missign glyph' callback but this is quite tricky as there is state to
be kept)
making all math characters active and resolve to math could be a
solution too but this is not always wanted either (so we should need
exceptions etc etc then)
