You are right that some things need to be fixed in ConTeXt - if nothing else, the map file could be removed from type-one and type.map. (Do not bother if you don't understand what I have written - it's targeted to ConTeXt gurus. Any opinions?)

The file is missing, but all the needed definitions are inside ec-base.map (I guess, I don't find ec-bitstrea-charter.map anywhere in order to compare):

bchb8t CharterBT-Bold

bchbo8t CharterBT-Bold ".167 SlantFont"

There are these files present on TeX Live (they are not in minimals):

/usr/local/texlive/2008/texmf-dist/fonts/tfm/bitstrea/charter/bchr8t.tfm /usr/local/texlive/2008/texmf-dist/fonts/vf/bitstrea/charter/bchr8t.vf

But when I compare to LaTeX with the following code \usepackage[T1]{fontenc} \usepackage[charter]{mathdesign} it uses other font metric files: /usr/local/texlive/2008/texmf-dist/tex/latex/mathdesign/mdbch/t1mdbch.fd ... \DeclareFontShape{T1}{mdbch}{m}{n}{ <->s * [0.96] mdbchr8t }{} ... /usr/local/texlive/2008/texmf-dist/fonts/tfm/mathdesign/mdbch/mdbchr8t.tfm

I suspect that one might need to fix or improve typescripts. Do you have some visual examples to show the differences? It would be interesting to compare the differences between bchr8t and mdbchr8t and change typescripts if needed.

Moreover, math support would have to be added to typescripts - it could be based on mathdesign.

Thanks Mojca. Appreciate your response, though as you said I do not really understand what I have to do, or if I could do anything. But a few things, (1) Regarding the visual examples, I could post the PDF file generated with Latex and Context. Is there a way to do that on this list? I noticed another difference, which is that the line spacing is slightly more in the Context document (compared to that compiled with Latex). In latex I chose \singlespacing. In Context, I did not change the default spacing. Is the default spacing different than singlespacing? (2) I was going to ask about the math support. You mentioned that it would have to be added to the typescript. How difficult is that? Does anyone know the commands that can be used for adding such support. Thanks. p.s. - BTW thanks very very much to the creators of Context for presenting us with this wonderful tool. I hope I can use it more and more for my work to create beautiful document.

ConTeXt has just other linedistances than LaTeX, that's all.

You can switch to a smaller distance with \setupinterlinespace[small] or with \setupinterlinespace[line=14pt] (fixed distance) or \setupinterlinespace[line=2.4ex] (font dependend distance)

I have a basic typescript for charter because I needed it in a document.

\starttypescript [math] [charter] [name] \definefontsynonym [MathRoman] [Charter-Math-Letters-Regular] \definefontsynonym [MathItalic] [Charter-Math-Letters-Italic] \definefontsynonym [MathSymbol] [Charter-Math-Symbols-Regular] \definefontsynonym [MathExtension] [Charter-Math-Extension-Regular] \stoptypescript

\starttypescript [math] [charter] [default] \definefontsynonym [Charter-Math-Letters-Regular] [mdbchr7m] \definefontsynonym [Charter-Math-Letters-Italic] [mdbchri7m] \definefontsynonym [Charter-Math-Symbols-Regular] [mdbchr7y] \definefontsynonym [Charter-Math-Extension-Regular] [mdbchr7v] \loadmapfile[mdbch.map] \stoptypescript

Thanks very much Wolfgang. I tried and it works for the most part in the simple document that I have. The parantheses, however, are not typeset correctly. They appear as horizontal arrows with only half a head, i.e., head only either above or below (sorry do not know the name of this symbol but I have seen it before). Regarding, the warning I mentioned earlier (pdfTeX warning: pdftex (file ec-bitstrea-charter.map): cannot open font map file), is there a way to fix that? Or, is there a need to fix that? Thanks.

The list only accepts very small files. So there are some options: - send the file to anyone interested (= the ones who replied to your thread) - upload to your own server temporary - (contextgarden.net needs a place to upload samples, but there's not much you can do about it apart from writing the scripts) - there are some public places that allow uploading files

See type-*.tex and math-*.tex in ConTeXt sources. Mathdesign seems rather sophisticated, so it depends to what extent one wants to reimplement the functionality in ConTeXt. Mojca

let's wait for results of the math-gyre project

Why, Charter is not part of the TeX Gyre project? Wolfgang
