Answer 1

You will have to download libcURL 7.21.7 (or some other binary compatible version) and recompile it with IDN support. You will need libidn installed in your system (including development files in the machine where you'll build libcURL).

Alternatively, you can also download the most recent version of libcURL, but you will likely have to recompile PHP (or at least the cURL extension) in that case.

Note that you can also preprocess your URLs using idn_to_ascii.
