[XeTeX] Greek (and other Unicode) letters in math mode

2011-05-31 Thread Gerrit
Hello, I always wonder why I can, if I write a formula in math mode, write latin letters (b, g etc.) as they are but have to write out greek letters like \alpha or \rho. Wouldn’t it be nice if I could write: $$ a^3 \cdot ψ \cdot Ω = ∞ $$ ? Or maybe even further: $$ a³ ∙ ψ ∙ Ω = ∞ $$

  I think, Xetex would then just need a mapping table converting Ω to \Omega before compiling. What do you think about that? Gerrit I think you should use package unicode-math and one of the few OpenType fonts that include a MATH table to achieve what you are asking. In different words,

Oh, great, thank you! Sometimes I am really surprised what is already there. :-) I’ll give it a try - although if the freely available Opentype fonts are not as beautiful as cmr...? I would say that this a matter of personal taste. What is beautiful for you is not necessarily beautiful
