@egreg What do you think is a sensible definition for \Box in unicode-math? 
\documentclass{scrartcl}
%\usepackage{amssymb}
\usepackage{unicode-math}
\begin{document}
$\Box$

@UlrikeFischer Perhaps \mdlgwhtsquare U+25A1 or \mdwhtsquare U+25FB

@Canageek pdfLaTeX? I can't imagine it would be that hard to fix.

@egreg There are a bit large compared to the ams square, but I will take it anyway. I don't want to load tons of math definitions and additional math fonts only for one symbol. Thanks

@UlrikeFischer With XITS Math, U+25FB seems alike; with Asana Math it's U+2B1C. It depends on the font, I'm afraid.

@egreg Imho it is quite okay if symbols looks different in different fonts -- I don't want to choose a symbol based on look but more on "meaning". But this is naturally difficult if you have a bunch of "squares".

@UlrikeFischer somewhere (oh tr25 I think) @barbarabeeton and Murray have a note about matching squares/diamonds/circles of various sizes....
@UlrikeFischer @egreg @barbarabeeton table 2.5 of unicode.org/reports/tr25

@DavidCarlisle Can we replace the squares by ducks?

@PauloCereda see my suggestion above for \Box, and the use that Ulrike suggested for it.

@egreg any insight on academia.stackexchange.com/questions/86337/… do Italian students really take 22 year long math courses?
 
egreg
egreg
4:36 PM
@StrongBad If you count 5 years of primary school, 3 of middle school, 5 of high school and 3 for the first level degree, you arrive at 16; 2 years of second level degree and 3 of PhD make 21.
@StrongBad That's a silly way to measure things.
 
StrongBad
StrongBad
@egreg but don't you take a bunch of courses each year during your degree?
 
egreg
egreg
@StrongBad It depends on how you count them. We had 15 year long courses in the four years for degree. Now things have changed, you can't count โ€œannualitiesโ€.

@yo' 801: Scientific Communication. I've heard other years it was really good, like when my boss was teaching it, but there was a group of us contemplating smuggling alcohol in to help pass the time.
I was lucky, I joined right before 802 was made mandatory, as it is both useless and a ton of work.
They make you write the first chapter of your thesis, which for us inorganic chemists is usless as we don't know what our thesis is about until we are almost done

@DavidCarlisle: British Library is the most awesome thing in the entire known universe.

But it is taught by natural product chemists (or was that year), who know what they are doing when they start then do that for a few years
@yo' Ok, that IS a good thing to learn.

@PauloCereda you found the paper you were looking for?

@StrongBad Wow, nice. That would be very difficult in chemistry, we specialize a lot.
 
StrongBad
StrongBad
@Canageek we specialized in a different way. I had a courses on the physics of sound, the peripheral auditory system, the brain stem, mid brain, cortex, head and neck anatomy, language and clinical problems in hearing. The rest were "practical" things like programing and signal processing and probability theory. I was taught a LOT about the ears but don't ask me about the eyes.

@JosephWright if you used DeclareTextComposite without having previously declared the accent command you got no error but it did some completely useless csname defined to be relax behaviour that would generate an error if the command was used. so I made it an error at the point of definition. but hyperref's puenc.def declares composites with newtie without declaring newtie... (but only for me, it seems:-)
@JosephWright Phew it's just in the svn version of ltoutenc.dtx not on ctan, so I have some time to update hyperref:-)
