Are you using LaTeX markup to get these symbols? Use $\alpha$ and
$\beta$ to get these two symbols.
Scott Randby
Sharon, the alpha and beta are encoded in UTF-8, these are passed through to the latex-file. The correct symbols will only show up in the pdf if your latex is UTF-8 capable. Some latex-implementations are, you can use \usepackage[utf8x,math]{inputenx} in your latex file, but I know, not all UTF-8 symbols are supported. For alpha to come out: \newcommand\textalpha{\ensuremath{\alpha}} is necessary (see http://www.latex-community.org/forum/viewtopic.php?f=9&t=2000 ) I couldn't get the beta to come out because it's not part of OT1. Anyone a good suggestion for this? I think Sharon has a valid expactation. regards, Joost >>>>> "Sharon" == Sharon Kimble <boudiccas@skimble.plus.com> writes: > From: Sharon Kimble <boudiccas@skimble.plus.com> > To: org-mode <emacs-orgmode@gnu.org> > Subject: [O] exporting α/β to latex/pdf > Date: 2014-05-04T17:13:45+0200 > I have these two symbols showing in my org-mode buffer with no > problems > ╭──── > │ alpha (ER-α) and beta (ER-β) > ╰──── > but they are not exported to latex/pdf.

How then can I do so please? The easiest solution is to use a modern TeX engine like XeTeX or LuaTeX along with a font with the required glyphs. I personally use XeTeX with Linux libertine fonts.

There are some caveats though. Clipping is a bit iffy, sometimes it warns as not supported but works anyway :-p. Sometimes it has trouble including slightly non-standard pdf images whereas pdfTeX works fine. There are also a few packages here and there that are still not completely supported. IIRC, either one of the TikZ math libraries or a 3rd-party TikZ library (maybe tikz-3dplot) is incompatible. That said, I attached a sample pdf with lots of unicode produced with XeLaTeX and Linux Libertine. As you can see, some glyphs are missing from Linux Libertine, but otherwise it looks pretty good! > > I personally use XeTeX with > > Linux libertine fonts.

For those who stick with pdflatex, you can also use "α" directly in the
org document, and define
#+latex_header: \usepackage[utf8]{inputenc}
#+latex_header: \declareunicodecharacter{03b1}{α}
Provided your file is indeed encoded in utf-8 (but why would you use any
other encoding?)
This simply tells the compiler to bind "α" to the unicode character
"greek small letter alpha" (U+03B1). If there is a lot of unicode in the
document, XeTeX/LuaTeX are definitely better choices.
Clément
Your example is quite motivating. With so many LaTeX sitting around its been hard to justify switching to the seemingly awesome XeTeX and LuaTeX despite the niceties. Being able to "just do Unicode" though... very nice especially from Org to TeX!

It seems to me, it talks about some Perl libraries that use LaTeX. If that is the case, then I can understand why that would be more involved. After all it is probably accessing more low-level features. > > Do you also need to do these? Or is there something more generic/uptodate? From a users perspective (I just call `xelatex' from the terminal, no fancy stuff), I found I need to do the same amount of searching as I did with pdfLaTeX. This is entirely driven by gaps in my LaTeX understanding. That said, there are cases where it has fewer features/bugs (I listed a few in my earlier email). Does that answer your question in anyway? If you faced any specific issues, I would be interested to know more. Cheers, -- Suvayu Open source is the future. It sets us free.

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---
Another is to use \textalpha and a package that defines it:
--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{textgreek}
#+LATEX_HEADER: \DeclareUnicodeCharacter{03b1}{\textalpha}
--8<---------------cut here---------------end--------------->8---
but then you have to install the package (and possibly some fonts as
well).

PS. So happy that gmane is back :-)

Oh my ! You are right of course. Sorry if I misled anybody.
