But that's not quite right: you end up with a circular definition (and both pdflatex and plain latex think so: they infloop).One way to fix it using a math alpha: --8<---------------cut here---------------start------------->8--- #+LATEX_HEADER: \DeclareUnicodeCharacter{03b1}{\(\alpha\)} --8<---------------cut here---------------end--------------->8---
Oh my ! You are right of course. Sorry if I misled anybody. Clément
