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 Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
