Dear Wolfgang. There is way to instruct to (\definefallbackfamily) to use shapes defined in typescript (eg: mi,mb)? \starttypescript [serif] [Minion Pro] \definebodyfont [default] [rm] [tf=name:minionproregular sa 1, it=name:minionproit sa 1, mb=name:minionpromedium sa 1, mi=name:minionpromediumit sa 1, bf=name:minionprobold sa 1, bi=name:minionproboldit sa 1] \stoptypescript

Is this for normal text or math?

For Math. The \tf and \bf commands in math aren’t font switches like in text.

Most math fonts come only with a regular style which provides upright, italic, bold and bolditalic symbols but all of them part of the same font, only a few fonts provide also a bold style (which is usefull in sections) which comes also with upright – and sometimes bold – symbols.

\setupbodyfont[xits]

\starttext

\startformula {\tf xyz} \; xyz \; {\bf xyz} \; {\bi xyz} \quad \mb {\tf xyz} \; xyz \; {\bf xyz} \; {\bi xyz} \stopformula

\stoptext

Depending on if the font project can arrange funding funding for it, the texgyre project will come up with a few bold math fonts (so bold + heavy) and sans math for titling etc. as well as a monospace math font (dejavu based) for editing and documentation.

Jose Luis Arellano mailto:jose.4rellano@gmail.com 10. September 2016 um 11:20 Thanks Wolfgang for explanation, as always very clear.

Another related question: If I want to use italic numbers in math, I use: \definefallbackfamily[...][math][...][tf=style:italic,preset=math:digitsnormal]

But I lose upright numbers this way.

How can I solve this issue. I've tried without success: \definefallbackfamily[...][math][...][preset=math:digitsitalic] Math symbols in MkIV are (mostly?) restricted to Unicode which doesn’t define italic digits (but you can choose between regular, bold, sans serif, sans serif bold and monospaced).

\setupbodyfont[xits] …

The STIX fonts, and XITS then, support Unicode math semantic styles. So perhaps the TeX commands should expand to these:

what tex commands ... we're talking characters and they don't expand there is a pseudo bold mode but the number of bold symbols is small so it's not that useful

\setupbodyfont[xits,10pt]

\setupmathematics[lcgreek=normal, default=normal]

If one writes ASCII ${\bf x} {\bi x}$, it would expand to the expected Unicode $𝐱 𝒙$.

That is already the case. Aditya

FYI, I found a neat trick: If one does not know the Unicode character, because the translation is correct, one can typeset using legacy TeX commands, and copy from the output PDF. It can then be used in the input file, if one so likes.

or maybe your editor has some selection menu

Some characters are hard to find in a Unicode symbols table. One example is lower case italic “ℎ”, others are the double-struck letters, which are also out of order. There are more examples, symbols that have lookalike non-math variants. So I made a alphanumeric text file for those. And there is also [1]. But if one has written and compiled some math, it may be quicker to copy from the PDF. 1. http://milde.users.sourceforge.net/LUCR/Math/unimathsymbols.xhtml

I use Xcode on MacOS (former OS X), which has very good Unicode support (including RTL scripts). There is a Unicode symbols table, but it is slow. One can also design one's own keyboard map, but that is very time consuming. Another input method is shown in the following video [1] where each symbol get its own command, e.g. \mbfitx is equal to {\bi x}. The source table mentioned in the video can be found on the STIX page [2].

In fact, I used the PDF copying method on a LaTeX unicode-math file. But the package expands ASCII to math italic, which I pointed out to the author last year, but got no reply. So ConTeXt seems to be more up to date and in line with Unicode.

The video speaks about a file stix-tbl.txt containing those translation commands, but on [2], the stix-tbl.* table files, not ending with .txt, do not contain those.

This works on MacOS 10.12 in any application that uses the standard text services. One has an XML .plist file as listed below. Then in such an application, one turns on "Text Replacements". (The video shows TeXShop.) Using the .plist file below, \mbfitx is translated into 𝒙. The replacement text can be anything. ---- <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <array> <dict> <key>phrase</key> <string>𝒙</string> <key>shortcut</key> <string>\mbfitx</string> </dict> <dict> <key>phrase</key> <string>𝒚</string> <key>shortcut</key> <string>\mbfity</string> </dict> <dict> <key>phrase</key> <string>𝒛</string> <key>shortcut</key> <string>\mbfitz</string> </dict> </array> </plist> ----

Hans Åberg mailto:haberg-1@telia.com 26. September 2016 um 11:00 FYI, I made interactive text substitutions (on MacOS) for the Unicode math letters plus a number of symbols. With it in hand, it is not particularly difficult to use Unicode symbols in the input file. Can you provide your file(s) for download?

I have made a new set, at [1], as before: Abbreviations using non-alphanumerical symbols now drop the leading "\", as they seemed to caused strange conflicts. Easier to type, but will have funny consequences in say C++ code. The alphanumerical abbreviations all start with a "\". I have changed the letters for bold, italic and bold italic, so as to not conflict with Greek two-letter abbreviations. In addition, added one letter shorthands for normal italic, as they are so common. Also, some ConTeXt commands added. Not all of these math letters work: the MacOS implementation is buggy. All symbols work, though. I also experimented with a variation where math letter abbreviations used non-alphanumerical symbols, but it turns out they are harder to use, because one needs to learn where they are on the keyboard. So it seems, using letter-only abbreviations is most efficient, except for a few common cases. 1. https://secure2.storegate.com/Shares/Home.aspx?ShareID=f20eb983-f0d9-4440-ab...
