leqslant for Cambria Math

leqslant for Cambria Math

[Michail Vidiassov]

Dear All,

using Cambria + Cambria Math (\usetypescript[cambria] \setupbodyfont[cambria])
makes Unicode math input and typesetting instantly possible
(great for a newbie, even if not FSF-kosher) -
but for missing glyphs for leqslant\geqslant.

What is the right way to fix or work around such problems?
(Complaining to MS does not count).

         Sincerely, Michail

There is not much that we can do when the glyph is missing from the font. 
In principle, we can create a fallback, but creating fallbacks for 
each and every missing glyph is not really an option.

The best solution that I can think of is

\let\leqslant=\leq

Then you will atleast get something meaningful.

"Not an option" - it impplies that there are many Unicode math fonts,
so one can not make workarounds for their individual glitches, but there 
is only one quality Unicode Math font - Cambria Math, one collaborative
playground development version - Asana-Math and, soon to be released (for years), 
STIX Fonts.
Or so I get it form a casual glance. Am I wrong?

      Sincerely, Michail

The soon to be released (for about six months now) minion math, and gyre 
math fonts to be started around the year end complete the list.

I am more concerned with the number of missing symbols. Where do we get 
the fallback symbol from? We can code it in metapost, or use it from lm or 
something else, but they will look ugly with rest of cambria.

at least we could start collecting missing bits and pieces (maybe a 
dedicated wiki page) so that at some point we can decide which ones to 
fill in with virtual glyphs (or take them from another font)
