Thanks for the answer. Is there another script font for LM, or for Palatino, which looks a little bit more readable than \cal in those fonts, and which can be used with the simplefonts mechanism? Best regards: OK

Hi Mikael, Thanks for your quick answer! Actually I used probably an inappropriate word when speaking about readability of the standard \cal in LM. Indeed they are readable, but for the particular case of ${\cal D}$, or ${\cal U}$ or ${\cal S}$, they do not correspond to the corresponding shape one finds in classical books of Analysis. On the other hand it does not contain lower case letters. In any case your solution below gives me exactly what I was looking for: %%%% begin example \definefallbackfamily[mainface][math][Asana Math][range={1D49C-1D4CF,212C,2130,2131,210B,2110,2112,2133,211B,212F,210A,2134}] \definefontfamily [mainface] [rm] [palatino] % or % \definefontfamily [mainface] [rm] [Latin Modern] \definefontfamily [mainface] [math] [Latin Modern Math] \setupbodyfont[mainface] \starttext ${\cal ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ ${\cal abcdefghijklmnopqrstuvwxyz}$ The space of distributions on $\Omega$ is denoted by ${\cal D}'(\Omega)$, while ${\cal S}({\Bbb R}^n)$ is the space of Schwartz functions, and ${\cal S}'({\Bbb R}^n)$ is its dual. \stoptext %%%% end example Since other people may benefit from it, I would like to update the wiki on the matter. But actually I do not understand what does the « range » mean in the example [range={1D49C-1D4CF,212C,2130,2131,210B,2110,2112,2133,211B,212F,210A,2134}] Could you please give a brief explanation so that I don’t write nonsense on the wiki?

Personally, I think that the \cal from Latin Modern is very readable (thus, I don't know what you are after). I tried some others, maybe you like one of them (I hope that the line breaks in the email will be OK):

\definefallbackfamily[mainface][math][TeX Gyre Termes Math][range={1D49C-1D4CF,212C,2130,2131,210B,2110,2112,2133,211B,212F,210A,2134}] %\definefallbackfamily[mainface][math][TeX Gyre Pagella Math][range={1D49C-1D4CF,212C,2130,2131,210B,2110,2112,2133,211B,212F,210A,2134}] %\definefallbackfamily[mainface][math][Asana Math][range={1D49C-1D4CF,212C,2130,2131,210B,2110,2112,2133,211B,212F,210A,2134}] \definefontfamily [mainface] [rm] [Latin Modern] \definefontfamily [mainface] [math] [Latin Modern Math]

\setupbodyfont[mainface]

\starttext ${\cal abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ}$ \stoptext

I'm glad it helped. The range gives the unicode slots where these letters "live".

Hans: Maybe this is a stupid suggestion, but could it be possible to have

\definefontfamilypreset [math:lowercasecalligraphic] as range={1D4B6-1D4CF,212F,210A,2134} and \definefontfamilypreset [math:uppercasecalligraphic] as range={1D49C-1D4B5,212C,2130,2131,210B,2110,2112,2133,211B} ?

Otared, If what I write above makes sense, then the setup will be the more readable

\definefallbackfamily[mainface][math][Asana Math][range={lowercasecalligraphic,uppercasecalligraphic}] \definefontfamily [mainface] [rm] [palatino] \definefontfamily [mainface] [math] [Latin Modern Math] \setupbodyfont[mainface]

This does already exist, take a look into math-act.lua. The presets are only needed when you want to use a text font as fallback because you have to set more values. Wolfgang

Hi Mikael, I created a page on the wiki where it is explained how to change calligraphic fonts in math: http://wiki.contextgarden.net/math_calligraphic I’ll add more comments and correct things on that page each time I learn something new in this regard… Thanks again: OK On 21 May 2014, at 21:10, Mikael P.

"However this does not work properly in mkiv ..."

this suggests that it could work in mkiv but math in mkiv has a completely different implementation so it isn't even supposed to work

maybe it's better to talk about mkiv as being the standard way and mkii being the 'old way' or so

You are right: I changed that page accordingly. All the best: OK

Thanks for the hint! I did run that file and then I thought my Mac was going to die since mkiv kept running and running… After several minutes I obtained an amazing PDF file of 2166 pages where every glyph can be seen on a beautiful page. Great stuff! Best regards: OK

Hi Aditya, Thanks for the hints: actually what I wanted to do was to use a calligraphic font which is a little bit more « script-y » as you put it (in particular for the letters A, B, D, S, U). Indeed using Khaled Hosny’s setup of xits one may get what I wanted to do. The solution suggested by Mikael is perfect when using Latin Modern in mkiv, since it shows that in mkiv it is possible, and very easy, to use any opentype font for the slots corresponding to uppercasescript and lowercasescript. When using palatino, I have to uderstand yet how to use palatino also in math mode… I don’t know what has to be changed in the following setup: \definefontfamily [mainface] [math] [Latin Modern Math] since replacing « Latin Modern Math » with « Palatino » does not work. Here is the example in which I would like to have palatino in math mode (for instance in \sin, or the variable x): %%%% begin example \definefallbackfamily[mainface][math][Asana Math][range={uppercasescript,lowercasescript}] \definefontfamily [mainface] [rm] [Palatino] \definefontfamily [mainface] [math] [Latin Modern Math] \setupbodyfont[mainface] \starttext This is \type{\cal}: ${\cal ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ This is \type{\cal}: ${\cal abcdefghijklmnopqrstuvwxyz}$ The space of distributions on $\Omega$ is denoted by ${\cal D}'(\Omega)$, while ${\cal S}({\Bbb R}^n)$ is the space of Schwartz functions, and ${\cal S}'({\Bbb R}^n)$ is its dual. Let $\phi(x) := \sin(|x|^2){\rm e}^{-|x|^2}$ and $T \in {\cal S}'({\Bbb R}^n)$ given above. \stoptext %%%% end example When one says \setupbodyfont[palatino] instead of \setupbodyfont[mainface] then the font used in math mode is also palatino, but then the uppercasescript is not what I would like to have… Best regards: OK On 21 May 2014, at 23:33, Aditya Mahajan wrote:

Hi all, It seems that the rsfs fonts (Ralph Smith’s Formal Script fonts) do not work: the procedure explained at the page

http://wiki.contextgarden.net/rsfs works fine with mkii, but not in mkiv.

I do not have the time to look into this in detail. But hopefully the hint below will help you get started.

If I understand you correctly, you are looking for a caligraphic font that is more "script-y" than the default \cal.

From what I understand, such glyphs are present as stylistic alternatives in unicode math fonts. See for example this thread

http://www.ntg.nl/pipermail/ntg-context/2010/050885.html

(I remember that there was another thread along these lines, but I cannot find it right now).

Found it: http://www.ntg.nl/pipermail/ntg-context/2011/061665.html

Thanks Mikael! That’s it: the real name of palatino in mkiv is TeX Gyre Pagella, and in math mode one has to use TeX Gyre Pagella Math… I am going to update the page on the wiki about calligraphic math. Another question (maybe Wolfgang has more to say about it): is the word « mainface » is a mandatory name for the font family which is defined? Because if I change it to « MyMainFace » then mkiv reports an error: Math error: parameter \Umathquad\displaystyle is not set Thanks again and best regards: OK On 22 May 2014, at 10:40, Mikael P.

What if you change those lines to

\definefontfamily [mainface] [rm] [TeX Gyre Pagella] \definefontfamily [mainface] [math] [TeX Gyre Pagella Math] ?

My guess is that palatino is a pointer to TeX Gyre Pagella.
