@cis Sorry, but if that were true, German wouldn't be a natural language. :) Of course we can find specific instances where German seems to be very specific compared to English, but in the general case, context dependence is simply a deep fact about how language works.
@Szabolcs Without a MWE impossible to say. But out of the box titling won't change anything with the spacing. So you must be doing something else.
@samcarter_looks_forward_TUG'21 wow, I didn't even know that one exists... Thanks. I'll probably wait with an answer until the feature is fully released (still in testing)
@AlanMunn Hiiiiiii :-) Last night I was dead: 36 degrees in the night. Impressive. And in the morning 45 :-(((((
@AlanMunn My question The best free online tools for writing in MathJaX has been closed. See the image below. My best regards, and my English language it is very poor also :-(
@PauloCereda -- Looks like a most congenial traveling companion, but I'm not sure how well the little one would fare if attacked by some person or creature intent on doing damage.
@FaheemMitha -- It has its ups and downs. Obviously I like it a lot, or we wouldn't stay The political situation at the moment could be improved, but we can hope. It's a great place for foodies, and a vibrant arts community (greatly disadvantaged by being shut down by the virus, but hanging in there). Good colleges and universities, but pitiful public schools (why???). Too little respect between the haves and the have nots. But hope. (That's the state motto.)
@FaheemMitha -- The NH motto really is that. At least it's the motto on the state's license plates. (It's left over from the U.S. revolution and the war of 1812.) But the inhabitants are mostly friendly.
If somebody knowledgeable of unicode-math can have a look at this... tex.stackexchange.com/questions/609201/… I am not sure that I have understood the problem nor why the workaround I suggested works (...)...
@Rmano The problem is that OpenType fonts as used by unicode-math do not explicitly contain the height and depth of individual characters, instead the actual drawing commands are analyzed to find the maximal height/depth. This does not allow to do tricks like manipulating the height and depth to make = and - appear similar.
@Rmano Is there a reason why the elements are individually centered instead of just aligning them in the math axis? Even without the +- issue, the v_0 seems rather high.
