I have these two symbols showing in my org-mode buffer with no
problems
--8<---------------cut here---------------start------------->8---
 alpha (ER-α) and beta (ER-β)
--8<---------------cut here---------------end--------------->8---
but they are not exported to latex/pdf. How then can I do so please?

Sharon.
