Seems like a small enough fix, I am good if you just put it in when you feel you are done @WarrenWeckesser. The unicode characters are a nice touch. Hmmm, we have a script flying around somewhere that prints similar tables, but I am too stupid to find it right now.

Hmmm... looks like shippable took off early for the weekend.

OK, nvm shippable. Let me put this in, the snippet runs fine for me.

Just happened to find it: print_coercion_tables.py

thanks! I've seen the output of that messing up failed tests recently, but I couldn't locate the source of it

Argh, apparently those Unicode checkmarks aren't drawn with the correct fixed-width when rendered on the web site (at least not with Firefox): https://numpy.org/devdocs/reference/ufuncs.html#casting-rules

If anyone sees a way to get the checkmarks to render correctly, let me know. Otherwise, I'll change the checkmark to, say, the letter Y for yes.

Hmmm, that is annoying, it works fine for me. My guess is that your font is missing the character, so that it switches over to another one for it? But if that is not just an outlier, we need to replace.

As far as I can tell (a few minutes of searching makes me an expert, right?), there isn't such a thing as a monospace font for all Unicode. Further investigation doesn't seem worthwhile at the moment. I submitted a pull request to change the checkmark to Y: #14595
