\nbsp usage

[Erik Butz <erik.butz@googlemail.com>]

Hi all,

I have a somewhat stupid problem, but didn't find a solution in the
manual or the list archive.
I want to use the \nbsp macro to generate a '~' symbol for Latex, but
I don't seem to get it to work correctly in my case.
I want to write 200~m²

If I do: 200\nbspm^2
it gets exported as: 200\nbspm$^2$,  so the symbol is not recognized.

If I do: 200\nbsp m^2
it gets exported as 198~ m$^2$, so in addition to the nbsp there is
another space at which a linebreak can occur

trying: 200\nbsp{}m^2 in analogy to other commands
I get: 200~\{\}m$^2$, so the parentheses are not recognized as
belonging to the command.

I am using the latest org version (just did a git pull and checked
that the behavior is still there) with emacs 23.1.1

Any hints appreciated.

Thanks,

Erik
