Hi all, on ctt, I just saw an annoucement for a xe(la)tex package which I found quite interesting. Here's the description: Location on CTAN: /macros/xetex/latex/ucharclasses This package addresses one of the few features where TeX still has to play catch-up to word processing programs: automatic font switching for different languages. In fact, it goes one better than word processing programs and comes with macros for inserting arbitrary code between text from different unicode blocks, by making use of XeTeX's little known "intercharclass" behaviour. I was wondering: is something similar possible in mkiv yet? I know that with the font fallback mechanism, it's trivial to change fonts for unicode ranges, but is it possible to change hyphenation patterns (or even insert "arbitrary code") according to unicode blocks? Would be quite helpful for those of us working with different scripts. All best Thomas
