I'm not sure if I understand the issue
- lm has + and - touching with the + in the same position as the regular +

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.

Re: [NTG-context] mathcases look different in mathalign and formula
On 3/28/2013 6:00 PM, Tobias Columbus wrote: Hi all, While playing with \startmathcases, I discovered some strange (maybe wanted?) behaviour of \startmathcases and \stopmathcases: - The interline spacing in mathcases is different depending on whether the mathcases are used in a mathalignment or a formula environment. - Lucida OpenType math has some nice curly brace that is also used in cases environments. However, if \startmathcases, \stopmathcases is used in some mathalignment environment and the cases contain subscripts, the curly brace disappears and some straight brace is used instead. a lucida issue (already looked into) - When using superscripts instead of subscripts, the curly brace reappears but the cases look like not vertically centered in both formula and mathalignment environments. I've added struts to the text column. This can be turned off with \setupmathcases[strut=no] The heights and depths and therefore the size of the curly braces is more consistent that way. I produced an example demonstrating the above observations. In my opinion, the disappearing curly brace is worst of all of them since one frequently has formulas both with and without subscripts on the same page and different braces are quite easily spotted. I'll clean up those macros (a bit more control and efficiency) when we're gone current (remind me).

Hi context list,
I noticed that the ∓ sign is a little higher than the ± sign, so that

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

CFF fonts do not store bounding box info anywhere, the engine just
calculates it based on glyph outlines. For TFM fonts the metrics can be
adjusted to achieve specific alignment.
