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?

Sharon.

Are you using LaTeX markup to get these symbols? Use $\alpha$ and
$\beta$ to get these two symbols.

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

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.  You can find my setup here:

The *easiest* solution is to just say \alpha and \beta in the org file
instead of α and β. But biting the bullet and adopting XeTeX or LuaTeX is
probably the *best* way to go (he says without ever having used either...)

Thanks for this, my initial thought was that I don't have either
xetex or luatex, but after a bit of digging around I found that
they are part of "texlive", which is already in debians repos, so
I'll have a play with it in the morning.

Thanks
Sharon.

Well put!

I really recommend using XeTeX for most things.  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!

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.

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!

Hi Suvayu

I am interested in switching over to xetex. I find however that things dont
work very easily and googleing around I find that some fixes are needed. eg
http://ledgersmb.org/faq/xelatex

Do you also need to do these? Or is there something more generic/uptodate?

Thanks
Rusi

I'm not sure what that FAQ is telling me.  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,

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).

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