While it's true that a few years ago most of fonts contained just a few math symbols, currently with the advent of Unicode things are changed dramatically, and the combination of true symbols (instead of macros like \alpha or \nabla), perhaps combined with a package like nath, can make formulas much clearer. I would separate math and text, but it happens that Unicode does not, iiar, so it seems that the only possibility seems that you have written. Definitely, kerning must not be killed. > should such an implementation be incorporated (somehow not this one), > - as a package, > - as a standard, > - not at all ... I would vote for a package (making it standard in LaTeX3 if necessary). Javier
