Startup error from RDKit Chemistry Type Definition Plugin: Where to change LC_NUMERIC?

Community Extensions RDKit

I installed the RDKit, but I get this error:


What should be don't is rather obvious, but where it should be done not so much... Where do I change the setting?

The locale is a system wide setting. If you don't want or can't change your system's locale, you can start individual application with a different locale by settings the corresponding environment variable in the shell from which you are starting KNIME, e.g.

export LC_NUMERIC=C
./knime

I found some information on "en" and "C": http://unix.stackexchange.com/questions/87745/what-does-lc-all-c-do

But I am still not sure which one I should choose... which should I?
