As documented here , the R iconv function does not work satisfactorily. Fortunately, a patch has been developed that addresses the problem (apparently).
My question is basic: how do I install the patch?
In the SO in English , there is an answer that points to the patch solution.
My infos:
R version 3.1.3 (2015-03-09)
MAC OSX 10.9.5
Platform: x86_64-apple-darwin13.4.0 (64-bit)
