DC: It’s a holiday in most of Europe, so that’s maybe why we don’t have
Fred and Rob.

NS: We can’t go through the main agenda without them since they are
involved in the issues in the agenda. I’ll open it up to other things and
start with something I have been dealing with in the operator dictionary...

Operator dictionary

NS: I ran into an issue with “:” and the operator dictionary. It has two
different kinds of usages: one has symmetric spacing and the other has
asymmetric spacing. Unicode seems to only have one kind of colon.

MS: There’s a colon in the 2200 block

NS: I see it -- it’s called “ratio” which is why I missed it. That’s the
symmetric use, so I’ll make “:” asymmetric.

DC: That’s backwards from TeX where “:” is symmetric and \colon is
asymmetric.

Large operator assembly (#198 (comment)
<https://github.com/mathml-refresh/mathml/issues/198#issuecomment-612727009>
)

NS: I have fontforge, but it doesn’t seem to know about the math table.
Does anyone have a tool to look to see if the bottom piece of an assembled
character has a depth.

[general discussion of what others do]

DC: I look into it after the call.
href

BM: I have a question related to where href can be. Have something like
F_c. I can put a def on the F or the c. If you hover the f or the c to
highlight. Not ideal, would like the msub to highlight.

BK: for security reasons, links should be limited. They have a lot of code
associated with them, so they have a wide footprint and hence a much larger
risk. Never would be able to use it with shadow dom.

BM: I’ll experiment with an mrow.

BK: You could also use CSS with hover to get it to highlight the entire
msub.

NS: I like that solution much better.

BK: Could be a solution to an even more difficult issue: embedded links.
Consider a binomial coef where the contents (the ‘m’ and ‘n’) wants to be
an href. Putting an href on the mrow would cause a problem with linking to
the ‘m’ and ‘n’, but if I put it on the parens and use CSS it would work.


NS: we get to end early. Meeting next Monday.
