[O] babel, beamer: Prevent apostrophe/single quote mangling, so examples can be reused from PDF

[Mikhail Titov]

Hello!

I’ve picked up some templates from orgmode tutorials and I can successfully 
create PDF made of beamer slides with babelized R code. The problem is that I 
can’t reuse text from pdf by copy-pasting like SQL I used in RODBC examples.

At some point all my single quotes are turned into something that is not even 
on my keyboard and looks like reversed back quote.

I’m not sure if mailing list can pass all these unchanged. I’m getting ’ 
instead of ' in the output.

What shall I look at to fix this? I really want all text to be easily reusable.

I feel like it is a LaTeX related problem since I see tex file as it is 
supposed to be. But there must be some workaround or at least warning for babel 
users of org-mode.

P.S. I typed in message in HTML mode and converted it to plain text later. And 
it looks like even MS Outlook did this conversion in text :(

P.P.S. I have the following in output tex file if it makes any difference

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

and I'm running MS Windows with latest org mode from git and MikTeX 2.9 .
