Hi context list,
I noticed that the ∓ sign is a little higher than the ± sign, so that
the + signs are at the same height. But this looks strange and
should be
changed.
Indeed. These look very odd. I tested this with cambria and the outcome
is similar, so this is not a font bug, but something wrong in ConTeXt's
math handling.
I'm not sure if I understand the issue
- lm has + and - touching with the + in the same position as the
regular +
- cambria has a gap between + and - and moves the + up and down
Afaik context isn't doing any magic here as these are precomposed
glyphs that directly map.
$a \ruledhbox{$+$} b \ruledhbox{$-$} c$
$a \ruledhbox{$±$} b \ruledhbox{$∓$} c$
they are 'binary' in math mode, just like + and -
The question is not about the shape of the glyph, but their location.
But after looking at the output of latex for CM and Cambria, I am no
longer sure what the correct output should be. For Cambria, ConTeXt and
LaTeX give similar outputs. For CM/LM they give different outputs.
it looks like the open type version has a fitting boundingbox while the
type 1 variants have a bit of the + sticking out:
\starttext
$x \ruledhbox{$\pm$} x \ruledhbox{$\mp$} x$
\stoptext
