"{" in Latex fragments

"{" in Latex fragments

[Christian Wittern]

Hi there,

In my org-mode document, I have a special sequence to switch to a Japanese
font defined as \J.  When using this, I have to do something like {\J
(Japanese characters here}.  However, when I run the org-mode export, the
braces "{" and "}" are escaped as \{ and \} and thus loosing their function.
 Is there some switch to prevent this from happening?  I would much rather
write \{ myself in the few cases where I in fact need it.

Any help appreciated,

Chris

yes.

but why don't you change the sequence? I mean:

from:

hello {\J ウ}

to 

hello  [\J ウ ] or: (\J ウ)

[] and () are not escaped

cheers,
Giovanni

Or what about \J{japanese characters here}?  I do the same with Hebrew,
\heb{לִפְנֵי יְהוָה} and (without claiming to have done extensive testing),
it seems to work.  Org mode is set up to let arbitrary macros of the format
\mymacro{data} pass through to LaTeX.  You might not even have to change
your definitions.

I think because the {}'s define a scope in latex and so the \J only
affects text surrounded by the {}.


For Christian, what about "\J{ text }" instead as org is careful to
let this type of construct go through unchanged, if I understand
correctly.  This does depend on how you have defined J but possibly a
slight redefinition would work (\newcommand{\J}[1]{.... #1}).

HTH,
eric

I had tried this first, but somehow the font was not switched back.  But now, looking at your example, I think it might have been because of a missing space.  I will give it a try.  

Thanks a lot,

Christian
