Re: [NTG-context] next beta

[Jeong Dal]

Dear Hans,

I updated ConTeXt beta today and run your sample for long formula.
It works nice and it is the feature what many math people want I think.
Thank you for your concern.

One thing that I’d like say is that a new line in the splitted long formula 
usually starts with operations in many math books.
But, in the ourput  of your example, every line ends with ‘+’ sign and begin a 
new line with a ‘number’.

Would you please check it once more?

Thank you again for your work, and have a nice weekend.

Best regards,

Dalyoung

The glyphs should be the same.

It is different font, so not compatible. Of the other fonts, STIX has very tall 
and narrow integral signs. There, Pagella looks better, but has strange looking 
Greek italic. There, Termes is even better, and nice weight on the sums, but 
has very narrow universal quantifiers. It has otherwise a nice weight in text 
boldface. Bonum has strange open Greek letters, and very thin, weird looking 
summation sign. I looked for serif DejaVu monospace, but could not find it: 
sans-serif thought to aid low resolution screens, but one is switching now.

It looks right in the PDF, but not when copying them and pasting into a text 
only file.

By contrast, copy-PDF paste text came our right here.

I get right spaces with latest beta from:

Sorry, but I’m afraid I don’t know what you mean. I get the same results
commenting \starttext.

I looked at various fonts, and they all have at least some math characters that 
look strange to me. So I figure one has to make a virtual font from ranges.

[NTG-context] STIX vs XITS

[Hans Åberg]

It says that XITS is an OpenType version of STIX on [1], but the latter now 
supports it. Does that mean that one can now use the latter directly?

Yes, it works in latest beta. There is a TeX Live updating utility, at least on 
the MacOS distribution, that allows for server synchronizations between the 
yearly updates.  

I found a strange bug with the \tt command, where the spaces disappear when 
copying from the PDF—see my other post in this thread. It occurs when adding a 
single symbol; it does not seem to matter which. It does not happen with 
\starttext, though.

Yes, that is the problem. It works fine with latest beta.

I found a strange bug with the \tt command: when copying from the PDF, the 
spaces disappear. With your header above, I get (the comments is the text copy 
from the PDF):

{\tt axiom A1. 푨 ⇒ 푩.}
%axiom A1. 푨 ⇒ 푩.

{\tt axiom A1. 푨 ⇒ 푩 α.}
%axiomA1. 푨⇒푩α.

That is, when adding a single symbol, above "α", but it does not seem to matter 
which, the spaces disappear.

It does not happen with \starttext, though.

The fallback mechanism has changed in a non-trivial manner since TL2017.  You 
have to go with beta.
