I've returned to my experiments with fonts and have a question: is there a way to use international characters in math like with LaTeX mathtext package? Or even as \text{} in AMS LaTeX?

compare $\hbox{\'e\'erste}$ and $\hbox{\tf \'e\'erste}$ and $\mbox{\'e\'erste}$

what you get depends on the encoding of the font in use, here you'l get compare garbage and okay and okay

so, you don't need any additional package

Thanks Hans, Wolfgang for your advice. \mbox and \text in newmath solves some problems like units, but what if I want bold roman math with international characters (or my own fonts) by default?

I'm trying to figure it out from sources, but it's very long and hard way.

I also ran into two problems concerning accented math while experimenting a bit (see below). Hans Hagen wrote:

To enable bold math by default write: \definetypeface[somename][mm][boldmath][latin-modern][default][rscale=1] % optional parameter rscale may be any number followed by \setupbodyfont[somename] if you want some other font, for example euler, choose one of the following lines: %\definetypeface[somename][mm][math][euler][euler] %\definetypeface[somename][mm][boldmath][euler][euler] But what exactly do you mean by bold math with accented characters? You can either typeset in mathmode, where you use \hat, \check, \acute, \grave, \bar, \vec, \dot, \ddot, \breve, \tilde or any other accent that you compose by yourself (poor results for accented characters, anyway). You can then set bold math to be the default. Or you can switch to text mode inside math using \hbox{...} as Hans described. If you want bold inside \hbox{...}, you probably have to define it in every \hbox manually or use bold font as default in the whole document. (If I'm wrong, please correct me.) Accented characters should work everywhere inside text mode as long as I understand. But quite some effort was put into ConTeXt to enable more advanced features regarding fonts, so it may be that ConTeXt sometimes accidentally fails to produce the desired result. Send an example if you think that it is causing troubles.

$\hbox{\tf \'e\'erste}$ and $\mbox{\'e\'erste}$

Is there any special reason that we have to write $\hbox{\tf ...}$? In plain TeX $\hbox{\v{c}}$ works just fine, while ConTeXt runs into the same kind of problems as last time with accented characters in MathML. ------------------------------------------------------------------------------------------- Can someone please try this: \definetypeface[somename][mm][math][euler][euler] \setupbodyfont[somename] \starttext $$\sqrt{\acute{a}+\bar{b}+\dot{c}}$$ \stoptext I don't get any accents.

No, I am.

You can verify further by adding: \loadmapfile[original-ams-base] \showmathcharacters

The normal text-ish accents are not present in the eulervm fonts. I suppose the rationale is that these are never to be used for text (but it becomes questionable when you don't have an overbar or dot!)

I have tried to figure out how to get them from other fonts, but am at a loss, in terms of the general case.

No one has mentioned it before now, so I didn't try that hard. :)

Anyone have any suggestions on what approach to take, or what they'd like to see?

Apart from creating some new virtual euler font with accents I can not see any solution. Beforementioned commands (\acute ...) do not work in \mbox and \hbox in math mode (writes about '{' and '}' missing). Another strange thing. After this sequence: \usetypescript [modern-base] [t2a] % just for example \setupbodyfont [modern] \definetypeface[mytf][mm][math][euler][euler] \startbuffer $$\sqrt{\acute{a}+\bar{b}+\dot{c}}$$ \stopbuffer \starttext \getbuffer \switchtobodyfont[mytf] \getbuffer \switchtobodyfont[modern] \getbuffer \stoptext Third formula remains roman. Why so? -- Radhelorn

Thanks for example. We're on the same way now ;-).

I meant not accented, but other alphabet (cyrillic in my case). Accented characters are composed from others, which is another case.

Is there any special reason that we have to write $\hbox{\tf ...}$?

Well, AFAIK in \mbox there is switch \mf (for 'math font'), which switches last font alternative even for math symbols. -- Radhelorn
