Dear Hans and other friends: I am a Chinese user of ConTeXt. Recently, I tried ConTeXt MkIV and test its Chinese typesetting. I am very glad to see MkIV can access my linux OS TTF&OTF fonts and give a good face of my article about lines breaking. But on the bilingual typesetting, such as Chinese sentences and English words appearance in a article at the same time , I found there are no good methods to solve the problem of setting fonts for them respectively. Now I had to handle it in this way: %%%% \definefontfeature[chinese] [mode=node,script=hang,lang=zhs] \definefontsynonym[songti] [name:simsun] [features=chinese] \definefontsynonym[Serif][songti] \definetypeface[song][rm][serif][songti] \setupbodyfont[song,12pt,rm] \font\enfont=name:msyh \def\en#1{% \,\bgroup\enfont #1\egroup\,% } \starttext 我用英文进行\en{Hello World}测试。 \stoptext %%%%%%%% I am eager to see full support for chinese and other Asian languages in ConTeXt MkIV. I am grateful to the developers. Thank you for your time and effort for continuous contributions!

Well, I am aware of that problem (I think Hans is aware of that too....). See the relative thread in mailing list archive (Jan 2008, I think). I mentioned the problem again in another mail to Hans this morning because more messages like this appeared on Chinese TeX related web forums these days (It's a good thing, more Chinese TeX Gurus love to play ConTeXt and LuaTeX ^_^). There are many ways to deal with that problem. in fact, add your \en macro into the method.hani() function of font-otf.lua is a quick and dirty hack. But I think there should be other more elegant ways to deal with it. perhaps: - assign an "english font" feature to "\definefontfeature" or "\definefontsynonym". When define a CJK typefaces, the corresponding English typeface can be defined by the user. switch to another font when needed (using the similar method as in font-otf.lua). - map the CJK part of a Chinese typeface and Latin part of a English typeface to one single virtual font, Use this virtual font for typesetting. Both of them are not hard to do technically compared what had been done before. So maybe we should wake Hans up to continue the CJK support? Zhichu Chen and I are eager to help whenever a localization problem is occurred. Yue Wang

well, examples of input as well as wanted output are needed then Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
Just an idea (I know nothing about Asian scripts and don't need those features myself): Would it perhaps possible to hook that font switch into the language mechanism? Like if I change the language between latin-script languages with {\de Deutsch} and get different typography, e.g. other quotation marks. Perhaps it would be a good solution to use something like: \setuplanguage[en]{fontfamily=MySerif} \setuplanguage[cn]{fontfamily=Songti} \mainlanguage[cn] \starttext 我用英文进行{\en Hello World}测试。 \stoptext At least that looks logical to me...

\starttext 我用英文进行{\en Hello World}测试。 \stoptext
At least that looks logical to me...
Yes, It is not only logic, but also useless and troublesome. especially typesetting a document with large amount of foreign words. Zhichu Chen and I are making a sample. Wait for a few days and we will post it to Hans.

FYI. I have recently tried to implement Korean typesetting with LuaTeX, using the second method you have mentioned, that is virtual font mechanism. It is, however, not for ConTeXt but for plain TeX, because I am ignorant about ConTeXt. http://people.ktug.or.kr/~nomos/mine/luatexko.tex http://people.ktug.or.kr/~nomos/mine/luatexko.lua http://people.ktug.or.kr/~nomos/mine/luatextt.lua On current stage, one of important features missing is supporting opentype GSUB, which now I am trying to understand how to implement. For testing, you have to install UnBatang.ttf, the most popular truetype font for Korean language. You can download this font from http://kldp.net/frs/download.php/1425/un-fonts-core-1.0.tar.gz or you may already have it if you use debian or ubuntu linux system. Then just make a document as follows and compile it with `luatex' command %%%%% \input luatexko ... some Korean document including english characters ... \bye %%%%% I hope my effort could contribute to developing CJK typesetting with LuaTeX.
