node-iconv used to be able to translit utf-8 chars (ça va) to ascii (ca va)
using setlocale("C.UTF-8") trick.
However, several libc6 version ago, that behavior changed, to the point
node-iconv fails its tests now.
I've failed to work around that, and i'm lacking libc6 knowledge to fix it,
or even properly report a bug about that. Please help me !
